Side shielded current in plane spin-valve

The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnet...

Summary:The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnetically decoupled from the hard bias materials by placement of spacers.
