Abstract

A magnetic element is generally provided that can be implemented as a data reader. Various embodiments may connect a magnetic stack to a top shield and separate the magnetic stack from a bi-layer side shield. The bi-layer side shield may have a fixed magnetization layer and a soft magnetic layer each magnetically isolated from the top shield.
