Abstract
A photoinduced change in the magnetic resonance parameters is observed in trilayer films of the system Fe/Si/Fe. The shifts of the resonance field and the character of the interlayer interaction are investigated as functions of the temperature, illumination of the films, and thickness of the silicon interlayer. It is found that at low temperatures the photoinduced contribution to the exchange interaction constant between the iron layers is antiferromagnetic.
