摘要：

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 degrees coupling with decreasing temperature. This was due to the strong temperature dependence of J(2) (biquadratic coupling), which outweighs that of J(1) (collinear coupling) at low temperatures.
