Spin Transport (IMAGE) Johannes Gutenberg Universitaet Mainz Caption Thermally excited spin waves carry a spin current from the ferromagnet (YIG in this case) into the metal layer. Depending on the YIG thickness and the interface condition the amplitude of the spin current as well as transmission properties change.
