Spin valve magnetoresistive head having magnetic layers with different internal stress
 A spin valve magnetoresistive head includes a first soft magnetic layer and a second soft magnetic layer having larger internal stress than that of the first magnetic layer. The larger internal stress of the second soft magnetic layer is created by injecting the second soft magnetic layer with a selected type of ion. Also included in the head is a nonmagnetic layer formed between the first soft magnetic layer and the second soft magnetic layer.
