Tuning ultrafast demagnetization with ultrashort spin polarized currents in multi-sublattice ferrimagnets

Abstract Femtosecond laser pulses can be used to induce ultrafast changes of the magnetization in magnetic materials. Several microscopic mechanisms have been proposed to explain these observations, including the transport of ultrashort spin-polarized hot-electrons (SPHE). However, currently such ul...
