Magneto-Optical Effects in Ferromagnetic Metals

摘要

The use of the Ferromagnetic Kerr Effect (FKE) is discussed in conjunction with band calculations for paramagnetic Ni and Fermi surface measurements with a view towards developing a reasonable range of models for the band structure of ferromagnetic nickel near the Fermi energy. The use of the FKE is illustrated by determining two typical models in this range for the case of rigid splitting of the paramagnetic d band structure near the Fermi energy. The extent to which these, as well as two earlier models give reasonable results for the FKE, other experimentally measured quantities, and the d band splitting is discussed. (Author)
