Abstract:	We report the effect of Mn doping on temperature-dependent magnetic properties of L10 FeMnPt (001) epitaxial films. (001) textured L10 Fe50-xMnxPt50 (x = 0, 5, 10, 15, 20 at.%) films were prepared by cosputtering Fe, Pt, and Mn onto MgO single crystal substrates at 550°C. θ-2θ XRD scans indicated the lattice parameter c increased whereas the ordering parameter S decreased with Mn doping. The thermal magnetic properties measured using a superconducting quantum interference device showed that Curie temperature TC could be reduced to 500 K with 15 at. Mn doping, but Ku was decreased to 1.6 107 erg/cm3. The relation of temperature-dependent anisotropy and saturation magnetization showed that it did not obey the Callen-Callen theory. © 2011 American Institute of Physics.
