Magnetic field effects on spin-split band and magnon transport in altermagnets and emergent compensated ferrimagnets
Kazushi Aoyama, Hikaru Kawamura
In altermagnets and fully compensated ferrimagnets, not only the electron band but also the magnon band exhibits spin splitting without net magnetization, which enables thermal act…

Triple- collinear state with compensated ferrimagnetic nature on frustrated kagome lattice
Kazushi Aoyama, Hikaru Kawamura
Spin-selective band splitting without net magnetization and spin-orbit couplings serves for a next-generation spin-current generator, and its typical platforms are altermagnets and…

Effects of the three-dimensional interplanar coupling on the centrosymmetric skyrmion crystal formation in the frustrated stacked-triangular Heisenberg model
R. Osamura, K. Aoyama, K. Mitsumoto +1
Effects of the three-dimensional (3D) interplanar coupling on centrosymmetric skyrmion crystal (SkX) formation is investigated via extensive Monte Carlo simulations on the frustrat…
