Abstract
L10-ordered alloys with high uniaxial magnetic anisotropy (Ku) are key materials for future spintronic devices to realize large-scale integration. In this study, we investigated the anomalous Hall effect (AHE) and anisotropic magnetoresistance (AMR) effect for FePt1-xPdx (001) epitaxial films. Highly L10-ordered structures and perpendicular magnetization were obtained for all the compositions. The FePt film exhibited the highest Ku and the largest anomalous Hall angle (θAHE) among the present FePt1-xPdx samples, and the values of Ku and θAHE were gradually decreased as the Pd concentration increased. In addition, the composition dependence of the AMR ratio showed a similar tendency to those for Ku and AHE. We discuss possible scenarios to explain these composition dependencies.
