ABSTRACT:
The method of fabricating an exchange-coupling film in accordance with the present invention comprises a multilayer body forming step of forming a multilayer body having an antiferromagnetic layer and a ferromagnetic layer laminated on the antiferromagnetic layer; and an annealing step of annealing the multilayer body in a magnetic field with a maximum temperature higher than a blocking temperature of the multilayer body by 15 to 60° C.
