Abstract
Described is an apparatus which comprises: an input ferromagnet to receive a first charge current and to produce a first spin current; a first layer configured to convert the first spin current to a second charge current via spin orbit coupling (SOC), wherein at least a part of the first layer is coupled to the input ferromagnet; and a second layer configured to convert the second charge current to a second spin current via spin orbit coupling (SOC).
