Abstract
Embodiments of the present invention relate to a galvanomagnetic device for use as a magnetic sensor or magnetic memory device. In a particular embodiment, the galvanomagnetic device comprises a non-conductive substrate, a first magnetic layer having a magnetic anisotropy perpendicular to the surface thereof, and a ferromagnetic second magnetic layer formed on the first magnetic layer. On the second magnetic layer, current electrodes are disposed to pass a current between two points, and voltage electrodes are disposed to detect a Hall voltage between two points perpendicularly to the current flow direction.
