Abstract
In HV-sputtered Fe100-xSix/Si100-yFey multilayers the antiferromagneti c coupling strength and the fraction of ferromagnetic coupling increas es with decreasing temperature. The ferromagnetic component can be exp lained by bridging along grain boundaries or by an Fe percolation mech anism in the nonmagnetic interlayers. Recent speculations that the mag netic coupling across the FeSi spacers is mediated by thermal excitati on of charge carriers are incompatible with our observations.
