Abstract: The thickness of an antiferromagnetic layer (IrMn) and the thickness of a nonmagnetic interlayer (Cu) are adjusted so as to be within the area surrounded by boundaries a to f on the graph of FIG. 6 in which the horizontal axis represents the IrMn film thickness and the vertical axis represents the Cu film thickness. Consequently, the interlayer coupling magnetic field Hin can be made to be 10 Oe or more, and the variation in the interlayer coupling magnetic field Hin can be made to be 2 Oe or less. In addition, in the area surrounded by boundaries a to f, at any IrMn film thickness, the Cu film thickness range in which the variation can be made to be 2 Oe or less can be set over a wide range, as compared with a known structure.
