Room-Temperature Field Switching of Exchange Bias Effect
A research collaboration led by PhD student Mihiro Asakura, Project Associate Professor Tomoya Higo, and Professor Satoru Nakatsuji has discovered an exchange bias effect at the interface between the Weyl antiferromagnet Mn3Sn and ferromagnets, which can be effectively controlled by applying a magnetic field without changing temperature. This study reveals that the controllability of exchange bias effect between ferromagnets and antiferromagnets can be improved by utilizing antiferromagnets with macroscopically broken time-reversal symmetry. These findings unveil a new functionality of the Weyl antiferromagnet Mn3Sn and lay the foundation for next-generation antiferromagnetic spintronics.

Maryland and Japan: Collaborations Toward the Quantum Industry of the Future
On April 14, 2025, World Quantum Day, Maryland Governor Wes Moore made his first official international mission to Japan and led a high-level quantum technology roundtable in Tokyo. The roundtable brought together prominent government, industry, and science leaders from Japan and the US to deepen international partnerships in the fast-growing quantum sector.
Trans-Scale Quantum Science Institute supported coordinating this event, and Prof. Satoru Nakatsuji moderated the roundtable. This involvement highlights our commitment to promoting international collaboration and global quantum research initiatives.
For more details of this event, please see the official press release from the Governor’s Office:
Creation of the basic theory of the material universe
By developing the forefront of quantum theory in material science, such as the understanding of spacetime structure by quantum entanglement, we create the basis of quantum technology.
Creation of quantum materials
We develop materials with exceptional properties that are safeguarded by quantum effects.
Creation of quantum information technology
We carry out research and development aimed at realizing quantum simulations and a wide range of other types of quantum information processing.
Creation of advanced quantum measurement technology
We develop ultra-high resolution quantum response measurement technology, and we create and observe quantum limit states under extreme environments.
