Abstract
Disclosed herein are magnetic sensors that include: a sensor stack having a front and an opposing back, wherein the front of the sensor stack defines an air bearing surface of the magnetic sensor, and the sensor stack includes: a free layer assembly having a second magnetization direction, that is substantially perpendicular to a plane of each layer of the sensor stack; and a stabilizing structure positioned away from the air bearing surface at the back of the sensor stack.
