Abstract
We review recent developments in the theory of surfaces and interfaces based on the disordered local-moment approach proposed independently by Hubbard and Hasegawa for finite-temperature band magnetism. We discuss the electronic structure and magnetism of 1) free surfaces of Fe(001), Ni(001) and Cr(001), 2) Ni thin films sandwiched by Cu, and 3) Co/Cr superlattices including the exchange anisotropy. These calculations account satisfactorily for relevant experimental results.
