Influence of miscut direction on magnetic anisotropy of magnetite films grown on vicinal MgO (100)
SHVETS, IGOR; ARORA, SUNIL; RAMOS, RAFAEL (American Institute of Physics, 2010)Ferromagnetic resonance (FMR) was used to study the influence of miscut direction on the in-plane fourfold and uniaxial magnetic anisotropies of epitaxial Fe3O4 films grown on vicinal MgO (100) surfaces. In-plane angular ... -
Large magnetorefractive effect in magnetite
ARORA, SUNIL; RAMOS, RAFAEL; SHVETS, IGOR (2010)We carried out a magneto-optical spectroscopic study of magnetite (Fe3O4) thin films and single crystals at optical wavelengths. We observed a relevant quadratic magneto-optic contribution that can be notably larger than ... -
The magnetic and magnetoresistance properties of ultrathin magnetite films grown on MgO substrate
SHVETS, IGOR; MCEVOY, CIARAN; RAMOS, RAFAEL (AMERICAN INSTITUTE OF PHYSICS, 2006)We report on the properties of ultrathin (2, 4, 6, and 8?nm) epitaxial films of magnetite, Fe3O4, grown on MgO (100). Atomic force microscopy image and V-I curves suggest that the films at this thickness are still continuous. ...
