Popis: Ellipsometry and the polar magneto-optical Kerr effect have been used in the photon energy range 0.65 eV⩽hv⩽5.4 eV to study sputter-etched manganese zinc ferrite (100) surfaces. With an annealed sample as a reference, a stratified media calculation indicates the presence of a paramagnetic surface layer of 8–40 nm thickness, depending on sputter parameters. Conversion electron Mossbauer spectroscopy and Rutherford backscattering spectroscopy fully confirmed these results.
