Abstract:
1. A magnetic sensor, comprising: a magnetic free layer wherein the magnetic free layer has a magnetization that is biased in a direction a parallel with an air bearing surface, but that is free to move in response to a magnetic field; a non-magnetic, electrically conductive layer formed adjacent to the magnetic free layer, and configured to accumulate spin polarized electrons at a side thereof based on a spin Hall effect when an electrical current flows through the non-magnetic, electrically conductive layer; circuitry connected with the non-magnetic, electrically conductive layer for supplying a current through the non-magnetic, electrically conductive layer; and circuitry connected to measure a change in electrical resistance between the magnetic free layer and the non-magnetic, electrically conductive layer.
