SAA2025 Symposium: Spintronics with Antiferromagnets and Altermagnets
The Trans-Scale Quantum Science (TSQS) institute co-organized, with the Institute for Solid State Physics (ISSP) and Johns Hopkins University, the International Symposium on Spintronics with Antiferromagnets and Altermagnets (SAA 2025). This event explores the frontiers of functional antiferromagnets, spintronics, and topological quantum materials.
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.
