Schematic Representation of Thermally Driven Spin Current (image) University of Illinois College of Engineering Share Print E-Mail Caption Ultrafast laser light creates heat transport through the nonmagnetic/ferromagnetic/nonmagnetic tri-layer. The thermal excitation in the ferromagnetic layer produces spin current in the adjacent nonmagnetic layer in a picosecond timescale.
