Magnetoresistive sensor capable of providing strong exchange coupling magnetic field, and thin-film magnetic head using the same
A twin boundary is formed in an antiferromagnetic layer (PtMn) that is not parallel to an interface between the antiferromagnetic layer and a ferromagnetic layer. With that crystal orientation, when the antiferromagnetic layer is transformed to regular lattices, the atomic array is changed to a mirror-symmetrical structure, and therefore lattice strain created in a direction parallel to the interface is relaxed. As a result, the transformation to regular lattices in the antiferromagnetic layer can be promoted effectively, and a strong exchange coupling magnetic field is produced.
