Abstract
Aspects of this disclosure relate to a resettable closed-loop multi-turn magnetic sensor. In one aspect, the sensor includes a nanowire forming a plurality of loops, a plurality of domain orientation sensors configured to detect locations of a pair of domain walls within the nanowire, and an initialization circuit configured to inject the pair of domain walls into the nanowire. The nanowire forms a closed-loop via a bridge crossing connecting two of the loops.
