APPARATUS, METHOD AND MAGNETIC SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a transducing element with reduced operational width which corresponds to a finer areal resolution in a magnetic device.SOLUTION: There are provided a free layer 132 that has a first areal extent that is sensitive to a magnetic field and a synthetic antiferromagnetic (SAF) layer 134 adjacent to the free layer and has a second areal extent that is greater than the first areal extent.
