Received 24 September 1990

We report the growth of Co-Pt superlattices along three different
crystalline orientations of Pt by MBE (molecular-beam epitaxy). [001],
[110], and [111] orientations of Co-Pt superlattices were grown using
seeded epitaxy techniques on GaAs substrates. The room-temperature magnetic
properties are strongly different for the three orientations. Structural
analysis of the superlattices reveals significant differences in interface
quality and defect structure for the three different orientations. These
effects may play a more important role in the origin of magnetic anisotropy
than previously assumed.
