Metallic superlattices composed of magnetic and non-magnetic constituents have been of recent interest both for the fundamental physical phenomena they exhibit, as well as for potential technological applications. Modern deposition and characterization techniques provide well-controlled material systems that display a variety of phenomena such as two-dimensional behavior, interface-induced magnetic anisotropy, enhanced magnetization, and long-range coupling effects. Although the critical temperature of the magnetic constituents in these superlattices can be very high in their bulk form, large reductions in the Curie point often occur for systems composed of a few atomic layers. These dimensionality effects frequently require the use of cryogenic temperatures to reveal their limiting behavior. Recent studies of single-crystal magnetic superlattices grown by Molecular Beam Epitaxy (MBE) are discussed.
