Abstract
The evidence of antiferromagnetic interlayer exchange coupling in Ni80Fe20 /Cr multilayers is reported. In Ni80Fe20/Cr multilayers, both the magnitude of the interlayer magnetic exchange coupling and the saturation magnetoresistance have been found to oscillate with the Cr spacer layer thickness with a period of about 13 Å. Moreover, a weaker absorption line above main line in ferromagnetic resonance spectrum for the antiferromagnetically coupling film with Cr layer thickness of 12 Å has been observed in perpendicular geometry, and the strength of the antiferromagnetic coupling has been estimated to be about 0.017 erg/cm2 as well.
