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

A TEM Structural Study of the Origin of Perpendicular Magnetic Anisotropy in Ultra-thin CoFeB Film

Perpendicular magnetic anisotropy (PMA) at ferro-magnetic transition metal/insulator interfaces has attracted intensive interest in the context of developing various spintronic devices. Magnetized out-ofplane magnetic tunnel junctions (p-MTJ) are now developed for spin transfer torque (STT) magnetic random access memories (STT-MRAM) applications where the strong perpendicular anisotropy origina...

Edge-modulated perpendicular magnetic anisotropy in [Co/Pd]n and L10- FePt thin film wires

Thickness modulation at the edges of nanostructured magnetic thin films is shown to have important effects on their perpendicular magnetic anisotropy. Thin film wires with tapered edges were made from [Co/Pd]20 multilayers or L10-FePt films using liftoff with a double-layer resist. The effect of edge taper on the reversal process was studied using magnetic force microscopy (MFM) and micromagnet...

Thin topological insulator film in a perpendicular magnetic field

We report on a study of an ultrathin topological insulator film with hybridization between the top and bottom surfaces, placed in a quantizing perpendicular magnetic field. We calculate the full Landau-level spectrum of the film as a function of the applied magnetic field and the magnitude of the hybridization matrix element, taking into account both the orbital and the Zeeman spin splitting ef...

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...
