Abstract

An electrical device includes a current transport layer made of an anomalous Hall material. The electrical device also includes a first ferromagnetic island in physical contact with the current transport layer and a second ferromagnetic island in physical contact with the current transport layer, the second ferromagnetic island oriented with respect to the first ferromagnetic island such as to concentrate a magnetic field, generated by current flow along a conducting surface of the anomalous Hall material, over the first ferromagnetic island and the second ferromagnetic island.
