Schematic Representation of the Experiment

Caption

From left to right: a spin up electron (red) scatters at the interface between YIG and platinum. In the collision, the electron spin reverses (green). This process generates a spin wave in the YIG, which propagates and gets absorbed at the second YIG-platinum interface. The spin is then transferred to an electron in the platinum, causing that electron to flip its spin direction (down to up). This spin flip will give rise to an electrical current, which is measured in the experiment.
