Illustrative Case of Featured Program “Covis” (Co-research Visit)
Covis is a team visit program combined with Long (Visiting Guest
Professor by ICC-IMR) and Short (Single Research Visit by GIMRT) stay,
started from 2022.
For the 1st case, IMR invited 2 researchers from CNRS, France. They
proceeded the experiments with very close discussion with HFLSM(High Field Laboratory for Superconducting Materials) researchers
under the theme, “High temperature superconductors for very high fieldmagnets beyond 30 T” . Effective collaboration with Covis scheme led
to publish a paper, DOI: 10.1109/TASC.2023.3242219. Furthermore,
the CNRS and HFLSM organize an international workshop on the theme
to form a strong and sustainable research partnership.

ICC-IMR Director

Hiroyuki
NOJIRIIn November 2023, IMR held the 6th Summit ofMaterials Science, SMS 2023. The international
conference SMS was created in 2012 to appeal therecovery from the Great East Japan Earthquake. It
is for the academic exchange based on the ideathat strong international cooperation in the ﬁeldof materials science is essential to create better
human society.
With the development of the Internet technology,
communication has been freed from theconstraints of place and time. In such age, why dopeople need to travel long distances to meet up?
In the ﬁrst place, traveling brings us the joy ofexperiencing new things with our full senses.
Encountering new materials, understanding
things from diﬀerent perspectives, and most ofall, meeting new people, these things would not
be possible without travel. And the mostimportant point is that unplanned or unexpectedencounters lead us to new worlds.
My ﬁeld of expertise, magnetism, deals with many
phase transitions. Phase transition is essentially acooperative phenomenon, and it appears theproperties that would never appear in individual
atoms or molecules. In another word, theinteractions among particles are necessary tocause phase transitions. This is why we see analmost inﬁnite variety of states in our world, eventhough the universe is made up of a limited
number of elements. I believe that suchmany-body eﬀect is what we expect forinternational conferences. Unfortunately, orfortunately, many-body interactions would be
diﬃcult even with today's most advanced
communication technologies.
Why researchers have almost inﬁnite topics todiscuss with each other in conferences? It isbecause we share a common ground of fact andtruth and an inexhaustible fuel of curiosity.
ICC-IMR has supported workshops, guest
professorships, fellowships, conference
attendances to support such activities. As a ﬁrst
attempt this year, ICC-IMR supported the travel of
6 students overseas and held a materials scienceschool for young generation in overseas. Throughthese new eﬀorts, we will contribute to building
new relationships among next generation
researchers from all over the world.
ICC-IMR believes that academic exchange isimportant and necessary activity in today's
divided world, and that it plays a role inconnecting the world for better futures.

Comments from a Visiting Professor

Daniel BRAITHWAITE
CEA Grenoble, FRANCE.
Although I have collaborated closely with professor Dai Aoki formore than 20 years, this was my ﬁrst opportunity to visit the IMR
lab in Oarai for a signiﬁcant period and carry out research here.
Our program was quite ambitious: to start to performmeasurements in a new compact diamond anvil pressure cellthat has been designed and constructed in Grenoble. Professor
Aokiʼs lab is impressively equipped for performing experiments
in extreme conditions of low temperatures and high magnetic
ﬁelds. However, at present this kind of pressure cell is not used,and quite a lot of preparations were necessary. Due to the kindwelcome and large expertise of all the members of the group it
was possible to do this eﬃciently and quickly. The lab is now
rather well prepared to use diamond anvil cells, with thepossibility to liquefy argon, and to measure ruby ﬂuorescence atliquid nitrogen temperatures. My 6 week stay, during which oneof our PhD students from Grenoble was also able to visit for 3weeks, was suﬃcient to ﬁnish this preparatory work and performthe ﬁrst measurements on a sample of UTe2 in the new pressure
cell. Using the Dynacool PPMS system we performed calorimetry
measurements under pressure at low temperature and undermagnetic ﬁeld with the possibility to rotate the pressure cell andso study the eﬀect of the ﬁeld orientation in relation to thesampleʼs crystallographic structure. This is, to my knowledge, aﬁrst worldwide, and an extremely powerful technique for theextremely anisotropic superconductor UTe2, allowing us todetermine the angular dependence of the critical ﬁeld underpressure and so gain information on the eﬀect of pressure on
the eﬀective mass and the band structure. These importantresults open huge possibilities for our future collaborations.
This visit was also amarvelous opportunity
to learn from theeﬃcient organization
and working attitude in
the laboratory, and also
to discover and enjoy
the beautiful
surroundings and richculture of Ibaraki.

Department of Civil and MechanicalEngineering, Technical University ofDenmark (DTU), Denmark.
As a recipient of the ICC-IMR fellowship award, I had theincredible opportunity to spend two months as anexternal researcher at Furuhara Lab. This experience wastruly a once-in-a-lifetime chance. The lab contains
state-of-the-art facilities and was populated by incredibly
kind, intelligent, and hardworking individuals who not
only taught me a great deal but also made my time inJapan truly enjoyable. They generously assisted me not
only with my research and experiments but also inunderstanding Japanese culture and lifestyle. Particularly,
the guidance and support from Professor Dr. Tadashi
Furuhara and Professor Dr. Goro Miyamoto greatly
enriched my comprehension of my PhD project andresearch outcomes. I feel immensely honored, inspired,and fortunate to have been part of such an outstanding
laboratory.
Despite my short stay, I made signiﬁcant progress. My
focus was on characterizing the martensite microstructure
in a nitrogen-stabilized precipitation-hardenable steel
alloy using techniques like TEM and EBSD. Speciﬁcally, I
investigated the variant pairing tendency in developed
martensite and its correlation with nitrogen content. The
quality of the results I obtained enhanced my overall
understanding of the research I had conducted at DTU.
Outside the lab, Sendai city's fusion of modernity andtradition captivated me. Exploring the city's vibrantatmosphere and historical sites was a delightfulexperience. Additionally, I had the chance to join theannual lab trip to Urabandai active resorts in Fukushima,
which exposed me to some of the best and breathtaking
natural beauty I have ever experienced. Overall, Japan'srich cultural heritage, blending centuries-old traditions
with technological advancements, left an indelible markon me.
In closing, my deepest gratitude extends to ICC-IMR andthe entire Furuhara Lab for their warm hospitality. I
eagerly anticipate future collaborations, nurturing newprojects, and knowledge exchange between Furuhara Lab
and my team at DTU, Denmark.

Summit of Materials Science SMS 2023 and Global Institute forMaterials Research Tohoku (GIMRT) User Meeting 2023 , November 20-22, 2023
The 6th SMS was successfully held at IMR
auditorium with almost 200 of participants(including online participants) in 3 days fromNovember 20 to 22. All speakers gathered ina hall after an interval of four years since thelast onsite meeting of 4th SMS held justbefore the pandemic.
The Conference started with the welcome
greetings by Prof. Takahiko Sasaki, Directorof IMR, Prof. Hideo Ohno, President of Tohoku University and Mr. Koji Yanagisawa,
Director of Scientiﬁc Research Institutes Division, MEXT (Ministry of Education, Culture,Sports, Science and Technology). The auditorium was fulﬁlled with over a hundred ofparticipants from all over the world.
The conference was divided in 9 ﬁelds, “Superconductivity”, “Quantum Materials”, “ExoticSpin Systems”, “Material Design and Informatics”, “Spintronics and TopologicalPhenomena”, “Functional Materials”, “Nuclear and Irradiation”, “Advanced Metallurgy ‒3D Printing and Nanomaterials” and “Hydrogen Materials”. A hot discussion wasexchanged at every ﬁeld, and a discussion sometimes extended for a break.
In the evening of 2nd day, the poster session was held. Researchers and students
presented their recent research topics. The discussion was overﬂowing with excitement
and enthusiasm and continued until late at night.
The total number of speakers were 48 this time. 20 were invited, in which 11 were fromoverseas, and 28 were contributed or short speakers. Not only senior researchers, but also
young and energetic speakers expressed lively their recent cutting-edge research topics.
