Abstract

The detailed temperature dependence of interlayer exchange coupling in Fe/FeSi multilayers prepared by ion beam sputtering was investigated and compared with the data for Fe/Si multilayers. Significant differences between interlayer exchange coupling in Fe/FeSi and Fe/Si multilayers were observed. The coupling between Fe layers in Fe/FeSi multilayers showed a transition from antiferromagnetic to 90° coupling with decreasing temperature. This was due to the strong temperature dependence of J2 (biquadratic coupling), which outweighs that of J1 (collinear coupling) at low temperatures.
