Title: Scaling of the anomalous Hall effect in epitaxial antiperovskite Mn{sub 3.5}Dy{sub 0.5}N involving multiple competing scattering mechanisms

Abstract

Anomalous Hall effect (AHE) has been studied for ferrimagnetic antiperovskite Mn{sub 3.5}Dy{sub 0.5}N film grown by molecular-beam epitaxy. Reflective high energy electron diffraction and transmission electron microscopy demonstrate the high quality of the film. We have used a scaling involving multiple competing scattering mechanisms to distinguish variations of contributions to the AHE by heavily doped Dy. The scaling analysis revealed that the heavily doped Dy has dramatically modified the skew scattering part of the AHE in Mn{sub 4}N and Mn{sub 3.5}Dy{sub 0.5}N has a totally different scattering mechanism from an undoped film.
