At least, an antiferromagnetic layer 4, a magnetization fixing layer 12, a non-magnetic layer 9, and a free layer 10 are successively formed. The magnetization fixing layer 12 or the free layer 10 is provided with a layered ferrimagnetic structure which comprises a pair of magnetic layers 5 and 8 through the intermediary of a non-magnetic intermediate layer 6. In the layered ferrimagnetic structure, a surface oxidation layer 7 is formed on the surface of the non-magnetic intermediate layer 6 to the side of the non-magnetic layer 9.
