ABSTRACT:
A magnetic head includes a magnetoresistive element. The magnetoresistive element includes a first magnetic film having a fixed magnetization direction, a second magnetic film having a fixed magnetization direction, a third magnetic film having a rotatable magnetization direction, a first nonmagnetic film, and a second nonmagnetic film. The first magnetic film, the first nonmagnetic film, the third magnetic film, the second nonmagnetic film, and the second magnetic film are stacked in this order.
