I visited the ISSP from August 1 to November 30, 2007. During this time, I investigated novel magnetic andsuperconducting order in strongly correlated electronic systems with the group of Prof. Tsunetsugu. This
collaborative effort turned out to be very fruitful and provides a firm basis to carry out collaborations in the future.
During the visit, two problems have been addressed and significant progress was made in each of these. Work on thefirst problem with Prof. Tsunetsugu has lead to an understanding of a new class of topological defects in pair density
wave superconductors. Work on the second problem has progressed well. In this problem, Dr. Hattori also madesignificant contributions. This work addressed the possibility of composite order (also known as nematic order) inunconventional superconductors.
In addition to the excellent scientific collaboration, my visit to the ISSP was also an enjoyable experience for myfamily and myself.

The main reason for this was the outstanding support provided by the ISSP for visiting

scientists. The help of the International Liaison Office staff, in particular, that of Ms Kameda and Ms Kubo wasindispensable. Ms Kameda and Ms Kubo were always very helpful and tried their best to address any request we
had. We very much appreciated this help and could not have done without it. Also of tremendous help were Ms.
Habu and Ms. Tsuji who work for the division of condensed matter theory.
My three children attended Toyofuta elementary school which is located very close to the ISSP. As far as I amaware, this is the first time that a visiting scientist at the ISSP has had children in a Japanese public school. My
children had taken only a beginning Japanese course before arriving, so there was a large language barrier. To help
ease this barrier, the school arranged for a private Japanese tutor that my children visited twice a week. Overall,this turned out to be an excellent experience. My children enjoyed Toyofuta elementary school and will have fondmemories of it. A variety of people helped us to communicate with the school. In particular Ms. Kameda and Ms.
Onuki helped considerably, and we also had help from a variety of parents of other children at the school.
Also important to the success of my visit was the housing provided by the ISSP. We stayed in the Kashiwa
International Lodge, which is a series of furnished apartments available for visiting scientists. This Lodge isconveniently located close to the ISSP and places to shop. It is also of sufficient size for our family. The proximity toother families in the Lodge was very useful in many ways.
In summary, the visiting scientist position at the ISSP provided me with a fruitful scientific collaboration and myfamily with an unforgettable and enjoyable experience.

Near the end of my stay in the ISSP, I was asked to write an essay which can be anything but research. Niceexamples of essays written by previous visiting professors make me feel I have nothing else to say about this new
research institute filled with the sophisticated equipments and its beautiful surroundings. When thinking about
leaving for United States, I have a lot to tell to all friendly people in the ISSP.
As they come to this world, Japanese know God places them in a small island and leave them with very limited
resources and no oil. Perhaps, these make everyone here appreciate what they have and respect each other.
It was first time for me to contact with a government agent when I applied the resident card after arriving at
Kashiwa campus. Talking with the agent is like a reunion with an old friend. Even so, I was told that the
government agency here is blamed the most for not being polite enough in dealing with customers. My experience toextend my US passport before I left for Japan was not as pleasant as this. A lady receiving my case seems to have nofunction of smile.
The public transportation system in Japan is very impressive. It is so reliable that one can make a travel plan
down to minutes. Anyone who has a driving experience in the bay area in United States knows that highway 880
and 580 are like parking lots for the most time in a day, cars are burning gasoline for nothing. The BART ( the masstransportation system in the bay area ) system does not cover this far for some reason. I am thinking that thedesire for oil may not be so urgent if the money is used to build the transportation system in some highly populatedarea instead of spent on Iraq war.
While waiting at Osaka train station, I was watching a guy cooking noodle in a small booth nearby. Some white
hexagons are floating in a pot full with boiling water. Noodles are cooked by merging a net bowl inside the pot.
Initially I thought those hexagons are some kind of food. I was told that the hexagons are used to cover most surface
of boiling water, which prevents water from converting into steam. Keeping water boiling for a whole day heats up
the small room in the booth and adds a huge load for a AC to take the heat out. By using this small trick, bothheating and AC energy consumptions are reduced significantly. This zoom-in episode reflects how Japanese use somebasic science in their daily life in order to do their part for curbing the global warming.
I have poor capability to imagine what a modern society should look like. But, when you see metal detecting doors
everywhere, when you hear the news of school shootings, shopping mall shootings before you forget the last one,when you deal with a government agent through a liquid-crystal monitor or through a small and deep window,
something goes fundamentally wrong.
I miss all food in Japan, vegetable tastes like vegetable, fruits are tasty and more colorful. But what I miss themost is a peaceful and responsible society in Japan.

KCuCl3, which is a three-dimensionally coupled spin dimer system with a gapped ground state. The gap decreases
with applied pressure. The pressure dependence of the gap was obtained. A quantum phase transition (QPT) from agapped state to an antiferromagnetic (AF) state occurs at Pc = 8.2 kbar. For P > Pc, magnetic Bragg reflections wereobserved at reciprocal lattice points equivalent to those for the lowest magnetic excitation at zero pressure. Thisconfirms that the spin gap decreases and closes under applied pressure. The ground state for P > Pc can be describedby the coherent superposition of the singlet |0,0² and two triplet components |1,±1². To investigate the pressure
effect on magnetic excitations, we also carried out neutron inelastic scattering experiments at 4.7 and 6.4 kbar using
a newly designed cylindrical high-pressure clamp cell. A well-defined single excitation mode is observed. The
dispersion relations along four different Q directions were obtained. The softening of the excitation mode due to theapplied pressure is clearly observed. Using the random phase approximation, we have analyzed the dispersion. From
the analysis of both magnetic susceptibility data and dispersion relations, it was found that an intradimer
interaction decreases with increasing pressure, while sum of interdimer interactions increases. These pressure
dependences of the exchange interactions give rise to reduction in spin gap and the pressure-induced QPT from agapped ground state to an AF state in KCuCl3.

Prussian blue analogs, such as K0.4[Co1.3Fe(CN)6]•4.7H2O, are typical examples of multifunctional materials,
combining spin-crossover (SC) transition, magnetic ordering and photo-magnetic properties. Recently, the multistability was evidenced by magnetic investigations using different kinetics of temperature in the title compound [1].
By flash cooling (more than 100 K/min), a sizeable macroscopic fraction of the high temperature (HT) phase, that is
CoII (S = 3/2)-FeIII (S = 1/2), is trapped at low temperature in the Q-phase for which it corresponds the highest valueof the magnetization. This Q-phase undergoes a thermal relaxation at 160 K, at which the magnetization drasticallydecreases because thermal charge-transfer produces the non-magnetic state CoIII(S = 0)-FeII (S = 0) (LT-phase). On
31

the other hands, by slow cooling (~1 K/min) from the HT phase, the system reaches an intermediate (IM) state, themagnetization of which is located between that of LT- and Q-phases. In addition, the spontaneous charge-transfer
transition CoIII(S = 0)-FeII (S = 0)  CoII (S = 3/2)-FeIII (S = 1/2) is accompanied by a thermal hysteresis loop. To
understand the multistability of the present sample, we measured photo-induced magnetization, powder X-ray
diffraction under light and reflectivity measurement under pressure. Here, we report on result of reflectivity
measurement under pressure in Potassium Cobalt hexacyanoferrate.

Figure 1. Temperature dependence of magnetic susceptibility of
K0.4[Co1.3Fe(CN)6]•4.7H2O in several phases. High Temperature phasehas spin configuration of FeIII(HS)-CoII(HS) (1. High Temperature state).
The kinetic hysteresis loop is observed by slow cooling and heating (2Intermediate state). The spin state keeps the high temperature spin
configuration by direct insertion to 10 K (3. Quench Phase), which showshigh magnetic susceptibility. LT phase (FeII(LS)-CoIII(LS)) is obtained bythermal relaxation of Q-phase (4. LT phase). All susceptibilities were
measured with 1 K/min sweeping late.

Thermal expansion is important physical value. There are some methods to measure thermal expansion such as
electric dilatometer, X-ray diffraction and strain gauge. To make high pressure, piston cylinder cell and diamondanvil cell (DAC) are often used. Piston cylinder cell is available commercial strain gauge. On the other hand, it is toolarge to use in DAC. So we make micron size strain gauge and introduce the making process.
