Insulative in-stack hard bias for GMR sensor stabilization |
摘要 |
A GMR sensor is disclosed for sensing magnetically recorded information on a data storage medium. The sensor includes a ferromagnetic free layer and a ferromagnetic pinned layer sandwiching an electrically conductive spacer layer. An in-stack, electrically insulative hard biasing layer is adapted to bias the free layer to a neutral magnetic domain orientation when the sensor is in a quiescent state with no external magnetic fields.
