Magnetoresistance sensor having an antiferromagnetic pinning layer with both surfaces pinning ferromagnetic bias layers |
摘要 |
A magnetoresistance sensor structure includes a magnetoresistance sensor having a sensor surface plane and having a free layer. An upper antiferromagnetic layer overlies at least a portion of the free layer, and an upper ferromagnetic layer overlies and contacts at least a portion of the upper antiferromagnetic layer on a contact face lying parallel to the sensor surface plane, so that the upper antiferromagnetic layer lies between the upper ferromagnetic layer and the free layer. The magnetoresistance sensor may be a giant magnetoresistance sensor or a tunnel magnetoresistance sensor.
