Abstract

A magnetic sensor includes a channel layer, a magnetization free layer placed on a first section of the channel layer, and a magnetization-fixed layer placed on a second section of the channel layer. A thickness of the channel layer of the first section is different from a thickness of the channel layer of the second section and a resistance of an interface between the channel layer and the magnetization free layer is lower than a resistance of an interface between the channel layer and the magnetization-fixed layer.
