摘要：

This Letter reports the results of giant magnetoresistance (GMR) and magnetic hysteresis measurements on sputter-deposited Co/Cu multilayers with random or highly oriented (111) textures. The multilayers were designed to be at the second maximum of the oscillatory exchange coupling and were deposited on to ion beam etched (111) Si substrates. We find that randomly oriented multilayers exhibit clear antiferromagnetic coupling and similar to 20% GMR, whereas (111) oriented multilayers are ferromagnetically coupled and show near-zero GMR.
