Thin-film magnetic head provided with magnetoresistive thin-film element
A thin-film magnetic head provided with a magnetoresistive thin-film element includes a laminate including an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer, and a free magnetic layer. At both sides of the laminate, soft magnetic layers, secondary antiferromagnetic layers, and conductive layers are formed. The antiferromagnetic layer generates a unidirectional exchange coupling by heat treatment to fix the magnetization of the pinned magnetic layer, and the secondary antiferromagnetic layers generate a unidirectional exchange coupling as deposited without heat treatment.
