Layer-dependent magnetization at the surface of a band-ferromagnet

Abstract

The temperature-dependence of the magnetization near the surface of a band-ferromagnet is measured with monolayer resolution. The simultaneous application of novel highly surface-sensitive techniques enables one to deduce the layer-dependent magnetization curves at a Fe(100) surface. Analysis of data is based on a simple mean-field approach. Implications for modern theories of itinerant-electron ferromagnetism are discussed.Comment: 4 pages, 1 figure, Phys. Rev. B, rapid (in press
