摘要
NiFe (20 Angstrom)/Mo multilayers were prepared by magnetron sputtering. We found typical oscillations of the interlayer coupling as a function of the Mo layer thickness with the same period as those in Fe/Mo multilayers (around 11 Angstrom). However, the oscillation phases in NiFe/Mo and Fe/Mo are almost exactly opposite. The magnetoresistance measured at the first antiferromagnetic coupling state is very small.
