Center for Advanced
High Magnetic FieldScienceIntroduction
Experimental science leads to new findings throughobservation and ultimately drives universal principles
and/or fundamentals. Materials science, which studies
materials necessary for our daily life and modernindustry, clarifies the electric, magnetic, mechanical,
and thermodynamic properties of individual materials
by investigating responses to the change in externalparameters, such as electric field, magnetic field,pressure, and temperature. Therefore, a wide range ofthe external parameters, namely an enlarged
observation window, sometimes brings about thediscovery of new physical phenomena. It should bestressed that modern materials science has been grownby expanding the external parameter ranges. Magnetic
field, which interacts directly with the spin degrees offreedom and orbital motions of electrons, is a soft andprecisely controllable external parameter thatcharacterizes the nature of materials. In the presentCenter, very high magnetic fields, which are notgenerated in most other laboratories, enable researchon various kinds of materials. High magnetic fields do
not only “investigate” the natures of materials, but also“change” them, and consequently provide observationof novel physical phenomena induced in very highmagnetic fields. In addition, the experiments employ
multiplexing of extreme conditions produced by very
high pressure and extremely low temperatures.
Research targets are magnetically frustrated systems,
quantum spin systems, and strongly correlated electronsystems such as high-Tc superconductors and heavy
fermion systems. Focus on functional materials, like
topological and multiferroic materials, clarifies
electronic states.

Research Projects
The major research themes of this Center are:
1. Studies of magnetic field-induced quantum phases
and phase transitions
2. High magnetic field studies and studies on quantum
criticality of strongly correlated electron systems
3. High magnetic field studies of functional materials
4. Development of experimental apparatus utilized
under multiplexed extreme conditions.

The History and Present Organization
The “High Magnetic Field Laboratory” was founded in1980 by emeritus Professor Muneyuki Date as the highmagnetic field facility of the Faculty of Science. In
1987, the Laboratory was reorganized as a division ofthe Research Center for Extreme Materials. The Center
was subsequently reorganized twice, in 1996, as the“Research Center for Materials Science at Extreme

Conditions”, and again in 2006, as the “Center forQuantum Science and Technology under Extreme
Conditions”. From April 2014, the high magnetic field
division in the last KYOKUGEN center started as anew center named “Center for Advanced High
Magnetic Field Science” attached to Graduate Schoolof Science.

and Center signboard
The Center consists of the following five divisions:“Research division of physics I”, “Research division ofphysics II”, “Research division of chemistry andbiology”, “Research division of cooperation”, and“Support division for joint-use”. The steeringcommittee of the Center is operated by members
elected from some departments in Graduate School ofScience. The full-time members in the Center conduct
research and education as a cooperative class and anundergraduate course in the Physics department.

According to “High Magnetic Field Collaboraory(coined word: collaboration + laboratory) Plan” basedon “Master Plan 2014” formulated by Science Councilof Japan, the plan is to build a national joint-usage
research base. As a first step, the steering committeeof “Pulsed High Magnetic Field Collaboratory” wasestablished by our Center and International Megagauss
Science Laboratory in the Institute for Solid State
Physics, The University of Tokyo, and the national
joint-usage research started from the fiscal year 2016.
From the fiscal year 2020, new national joint-usage
program has started with High Field Laboratory for
Superconducting Materials in the Institute forMaterials Research, Tohoku University. In addition, anagreement of cooperation and collaboration of highmagnetic field research with research centers in Kobe
and Fukui Universities (KOFUC network) wasformalized on April 1, 2014. On November 1 in 2018,
our Center formalized the same agreement with a highfield research center in Osaka Prefecture University(Present: Osaka Metropolitan University). Under these
agreements, academic exchanges and personnel
training are conducted through these cooperation andcollaboration.
