1. A device for generating a spin current, the device comprising:
a planar component for generating an out-of-plane orbital current via Orbital Hall Effect (OHE) of an in-plane charge current flow within the planar component, wherein the planar component is an ordinary metal lacking a 5d electron shell;
a layer of a heavy metal in electrical contact with a face of the planar component, for converting the out-of-plane orbital current to an out-of-plane spin-current, wherein the heavy metal has a 5d electron shell;
a ferromagnetic component above the heavy metal layer;
two electrical terminals connected to different sides of the planar component; and
electrical resistance measuring apparatus connected between the two electrical terminals.
