ABSTRACT
The room-temperature magnetic properties and magnetization reversal process of ordered (FePt)[sub 1-x]C[sub x] thin films, prepared by a cosputtering technique on MgO (100) substrates held at 400 °C substrate temperature, have been studied. Perpendicular magnetic anisotropy was obtained for the films with carbon concentrations up to 25 vol % and coercivity enhancement was observed with small carbon-doped FePt thin films. A clear spin-reorientation transition from perpendicular to the in-plane direction was observed with an increase in carbon concentration. The observed magnetic properties are intercorrelated to microstructural changes that occur as a function of the carbon doping. © 2003 American Institute of Physics.

    Thin epitaxial Fe films grown on GaAs(100) and Ga0.8In0.2As(100) substrates were investigated to determine how tuning the lattice constant mismatch between the Fe and the substrate may change the in-plane anisotropies and the magnetostriction.
