Influence of the antiphase domain distribution on the magnetic structure of magnetite thin films
نویسندگان
چکیده
A long-range ordered magnetic domain structure was found in magnetitelike Fe3− O4, 0.03 thin films prepared by molecular beam epitaxy on MgO 100 substrates. The stripelike magnetic domain structure arising after suitable postprocessing differs significantly from earlier observations. The field-dependent domain structure was investigated by magnetic force microscopy in external magnetic fields. The magnetic domain structure results from a moderate perpendicular anisotropy. The domain structure is pinned, and the pinning centers arise from the magnetite antiphase domain structure. © 2006 American Institute of Physics. DOI: 10.1063/1.2356308

متن کاملEffect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...
متن کاملObservation of antiferromagnetic coupling in epitaxial ferrite films
Defects in ferrite can change the local magnetic coupling from ferromagnetic to strongly antiferromagnetic. In eptiaxial magnetite Fe3O4 films, defects locally altering exchange interaction, i.e., “antiphase boundaries” APB , essentially determine magnetic and magnetotransport properties. We locally observed specific magnetization reversal events in epitaxial magnetite Fe3− O4/MgO films 0.03 by...
متن کاملInfluence of Co and Fe substitution on optical and structural properties of zinc oxide thin films
Zn0.97TM0.03O (TM = Co, Fe) thin films were deposited onto glass substrates by the sol–gel method and the effects of transition metals substitution on structural and optical properties of ZnO films were investigated. The X-ray diffraction patterns revealed that the films have wurtzite structure. Optical transmittance of the films was recorded in the range of 200 -800 nm wave length and the band...
