Structure and Ferromagnetism of Thin Magnetic Layers
Abstract We have recently succeeded in applying spin-polarized neutron reflectance at grazing angle of incidence to study the feromagnetic behaviour of thin magnetic films down to the monolayer thickness level. This technique allows us to determine the absolute value of the magnetic moments, as well as ferromagnetic ordering, as a function of temperature and thickness. Similar measurements using spin-polarized photoemission in a variable magnetic field endorse the neutron reflectance results. The films exhibit strong magnetic anisotropy effects which are structure and strain related. Detailed LEED measurements have established the degree of relaxation and strain. The results are discussed in the context of 3D to 2D magnetic scaling theories and predictions derived from local-spin-density functional calculations of the magnetic moments per atom as a function of lattice strain.
