The effect of low energy noble gas ion bombardment on the electrical and optical properties of Si(211) surfaces has been investigated by surface conductivity and field effect measurements, ellipsometry and AES. With this combination of techniques, in

The conversion electron Mossbauer spectra of CoFe2−xAlxO4 (x = 0.1, 0.3, 0.6, 0.8 and 1.0) were measured at room temperature. Cation distributions for all samples were derived and compared with the cation distributions as obtained for powdered samp

Mechanically polished mono-crystalline (100) manganese zinc ferrite samples have been investigated using magneto-optical spectroscopy and hysteresis loops. The as-polished (100) surface shows a thin damaged layer on top of a relatively thick highly c

The magneto-optical spectra of Co 1+ x Fe 2− x O 4 show with increasing Co 3+ content an increasing intensity of the 4 A 2 − 4 T 1 ( F ) and 4 A 2 − 4 T 1 ( P ) transition of Co 2+ at 0.8 and 2.0 eV. A decrease in the Co 2+ -Fe 3+ charge transf

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 calculati

The perpendicular anisotropy in (100)-textured CoFe 2 O 4 thin films is found to be due to a combination of magneto-crystalline anisotropy and stress-induced anisotropy. The magneto-crystalline anisotropy by itself is insufficient for potential use a

Spectroscopic ellipsometry and the polar magneto-optical Kerr effect (0.6 < hv < 4.5 eV) have been used to study non-destructively the influence of RF sputter etching on the magnetic surface properties of the (100) face of manganese zinc ferrite sing
