A variety of superlattices, multilayers and metastable solids                   will be fabricated by molecular beam epitaxy (MBE) and advanced                 sputtering, and characterized by x-ray diffraction, transmission                electron microscopy and other microstructure techniques.  In the                rare earth superlattices, the magnetic properties, tailored spin                structures and interlayer coupling will be explored.  Periodic as               well as aperiodic superlattices will be studied.  They will                     investigate the linkage of collinear and helical spin structures                in gadolinium-dysprosium superlattices.  Iron and cobalt based                  superlattices are well suited for the investigation of the                      magnetic properties of thin magnetic layers and effects due to                  layer thickness, crystalline orientation and interfacial                        coupling.  In multilayer systems, the behavior of thin alloy                    layers, both cryatalline and amorphous, and either ferromagnetic                or spin glasss, will be studied.  Magnetic surface anisotropy,                  its dependence on layer thickness and crystalline orientation,                  and the possibility of perpendicular surface anisotropy will be                 investigated in superlattice and multilayer systems.  A number of               manganese-based and iron-based metastasble alloy systems will                   also be studied.
