The Kerr Effect from first Principles Theory: Application to HCP/FCC Cobalt
We consider the macroscopic theory of the Magneto-Optical Kerr Effect. It is shown that the Kerr effect is zero without both spin-splitting and spin-orbit coupling. The origin of peaks in the Kerr signal is discussed. For the transition metals iron, cobalt and nickel these peaks arise from interband transitions. Results for the fcc and hcp forms of cobalt are presented and compared. Fair agreement with recent experiments is found. The effect of the lattice parameter and the Drudterm on fcc is also shown.
