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 ... -
Positive antiphase boundary domain wall magnetoresistance in Fe3O4 (110) heteroepitaxial films
SHVETS, IGOR; ARORA, SUNIL (2011)We observe a strong crystallographic direction dependence on the low-field magnetoresistance (MR) behavior of the epitaxial Fe3O4 (110) films grown on MgO (110) substrates. The sign of MR is positive when the current and ... -
Strain relaxation studies of the Fe3O4/MgO (100) heteroepitaxial system grown by magnetron sputtering
SHVETS, IGOR; ARORA, SUNIL (2004)Detailed strain relaxation studies of epitaxial magnetite, Be3O4, films on MgO(100) substrates grown by magnetron sputtering reveal the accommodation of strain up to 600 nm thickness, a thickness far above the critical ...
