Polar magneto-optical Kerr effect for low-symmetric ferromagnets

• The polar magneto-optical Kerr effect (MOKE) for low-symmetric ferromagnetic crystals is investigated theoretically based on first-principles calculations of optical conductivities and a transfer matrix approach for the electrodynamics part of the problem. Exact average magneto-optical properties of polycrystals are described, taking into account realistic models for the distribution of domain orientations. It is shown that for low-symmetric ferromagnetic single crystals the MOKE is determined by an interplay of crystallographic birefringence and magnetic effects. Calculations for a single crystal and bicrystal of hcp < 11 (2) over bar0 > Co and for a polycrystal of CrO2 are performed, with results being in good agreement with experimental data.
