Magnetoresistive (MR) element having a continuous flux guide defined by the free layer
Magnetoresistive (MR) elements having flux guides defined by the free layer are disclosed. The MR element includes a free layer, a spacer/barrier layer, a pinned layer, and a pinning layer. A back edge of the free layer (opposite the sensing surface of the MR element) extends past a back edge of the...

Zusammenfassung: | Magnetoresistive (MR) elements having flux guides defined by the free layer are disclosed. The MR element includes a free layer, a spacer/barrier layer, a pinned layer, and a pinning layer. A back edge of the free layer (opposite the sensing surface of the MR element) extends past a back edge of the spacer/barrier layer. The portion of the free layer extending past the back edge of the spacer/barrier layer defines a continuous flux guide. The flux guide is processed to reduce the conductive characteristics of the flux guide, thereby reducing current shunt loss in the flux guide. |
