Fe/Cu/Fe and Co/Cu/Co multilayers on Cu

The magnetooptical Kerr effect was used to search for evidence of the oscillatory antiferromagnetic (AF) coupling associated with the recently discovered giant magnetoresistance effect (GMR) in Fe/Cu/Fe and Co/Cu/Co multilayers. The GMR effect was reported in samples grown by magnetron sputtering methods on Si wafers. In the present work the multilayers are grown by molecular beam epitaxy (MBE) techniques on Cu
