Uniaxial magnetic anisotropy induced by vicinal surfaces in half metallic La0.7Sr0.3MnO3 thin films

Reorientation of magnetic anisotropy in obliquely sputtered metallic thin films

Reorientation in the magnetic anisotropy as a function of film thickness has been observed in Co-Ni and Co thin films, obliquely sputtered on a polyethylene terephthalate substrate at a large incidence angle ~70°!. This effect is a consequence of the low magnetocrystalline anisotropy of the films ~fcc structure of Co! and changes in microstructure from nuclei to columns according to the thickne...

Probing magnetic anisotropy effects in epitaxial CrO2 thin films

The magnetic anisotropy in ferromagnetic chromium dioxide thin films (Tc;393 K) grown epitaxially on ~100! TiO2 substrates, is probed using precise rf transverse susceptibility (xT) measurements. Singular peaks in xT are observed that are associated with the anisotropy (6HK) and switching (6Hs) fields in CrO2. Theoretical calculations of xT based on a simple coherent rotation model display rema...

Magnetic oxide nanowires with strain-controlled uniaxial magnetic anisotropy direction

While magnetic nanowires generally have a preferential magnetization direction along the wire axis to minimize magnetostatic energy, it is shown here for epitaxial magnetic oxide nanowires that substrate-induced strain can be used to tailor the magnetic easy axis in any direction. La0.67Sr0.33MnO3 LSMO nanowires were prepared by pulsed laser deposition of LSMO thin films on NdGaO3 NGO substrate...
