Abstract
Systems and methods are provided for manufacturing a magnetic recording sensor for use in a magnetic reader, such as a tunneling magnetoresistance (TMR) readers. The magnetic recording sensor can be manufactured by heating a substrate in a first chamber and depositing an antiferromagnetic (AFM) layer on the heated substrate. Additionally, a first pinned layer is added onto the AFM layer, and the substrate is subsequently cooled.
