[Tu-P1-D-03] Nonlinear spin current generation in altermagnets and f-wave magnets

〇Motohiko Ezawa¹ (1. The University of Tokyo (Japan))

Nonlinear spin currents are generated in altermagnets and f-wave magnets by electric field and temperature gradient. We propose nonlinear spin Seebeck diode in f-wave magnets. Perfectly spin-polarized third-order nonlinear currents are induced by applying elliptically polarized light in d-wave altermagnets.
