ABSTRACT:
An exchange coupling film comprising a first antiferromagnetic film, a ferromagnetic film formed as superposed on the first antiferromagnetic film, and a second antiferromagnetic film formed in the interface between the first antiferromagnetic film and the ferromagnetic film, characterized in that the first antiferromagnetic film has a crystal structure selected from the group consisting of tetragonal, body-centered cubic, and NaCl type and the second antiferromagnetic film of .gamma. phase M-Mn alloys with the crystal structure of face-centered cubic, wherein M stands for at least one element selected from the group consisting of Fe, Co, and Ni.
