The conditions under which high quality metal superlattices can be grown with sharp flat interfaces are described. The discussion is illustrated by examples that include the growth of rare earth superlattices in chosen orientations. It is emphasized that epitaxy makes the structure and properties of thin films differ from those of the bulk. In particular, the clamping of a magnetic film by its substrate modifies the magnetoelastic energy and consequently change the magnetic phase diagrams of individual layers. Experiments using MBE-grown antiferromagnetic rare earths films and their superlattices with Y are discussed in the light of these observations. 30 refs., 10 figs.
