Phonon-driven tuning of exchange interactions in Y3Fe5O12
Kunihiko Yamauchi, Tamio Oguchi
Yttrium iron garnet (Y3Fe5O12) is a prototypical ferrimagnetic insulator widely used in spin-wave and magnonic devices owing to its extremely low magnetic damping and long magnon p…

Spin-degenerate bulk bands and topological surface states associated with Dirac nodal lines in RuO2
T. Osumi, K. Yamauchi, S. Souma +13
Altermagnets are a novel platform to realize exotic electromagnetic properties distinct from those of conventional ferromagnets and antiferromagnets. We report results of micro-foc…

Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
