Ferrimagnetic insulators have gained much attention as material platforms with efficient magnetization dynamics. To date, epitaxial iron garnet thin films are the most widely used materials in emerging field of “insulator spintronics.” However, further advances this require overcoming disadvantages garnets—e.g., their complex structure, high growth temperature, incompatibility other crystalline...

Based on the spinor Boltzmann equation (SBE) formalism, we present a theory of temperature-dependent thermal spin–orbit torque for system in presence Rashba interaction. Under local equilibrium assumption, can expand distribution function around distribution; then, spin diffusion be derived from SBE, where transfer torque, orbit as well naturally obtained. It is shown that this originates tempe...
