Magnetoresistance oscillations with a period of two monolayers of Cr have been observed in Fe/Cr/Fe trilayers. Magneto-optic measurements were performed on the same sample in order to verify the periodicity and determine the nature of the coupling between the Fe layers. The saturation fields obtained from both the transport and optical measurements agree well at room temperature. These results indicate that the magnetoresistance is controlled by the coupling mechanism.
