Interlayer magnetic coupling (IMC) between Fe and Gd layers through Al spacer has been experimentally studied on [Al(RÅ)/Gd(40Å)/Al(RÅ)/Fe(20Å)]×N/Al(5Å) magnetic multilayers, where R=0, 5, 10, and 20 as nominal figures. Magnetization curves and the temperature dependence of magnetization are reported. Magnetic Compton-profile technique has been used to determine the amounts and the signs of spin magnetizations of Fe and Gd layers for R=5 and 20. A line-shape analysis of the magnetic Compton profile on the multilayer of R=5 has verified that the IMC is antiferromagnetic, and the negative small amount of magnetization of Gd layer exists even at room temperature under 1kOe, despite the absence of ferromagnetic magnetization of a Al(5Å)/Gd(40Å) multilayer at room temperature. The antiferromagnetic IMC has been confirmed in the case of R=0, 5 and 10, but the IMC is not observed in the case of R=20.
