Abstract

Thin films of Mn50BixAly were made using the co-evaporation method. X-ray diffraction measurements confirmed the presence of MnBi, and weak diffraction lines suggested the presence of a second phase, possibly the MnAl τ phase. Hysteresis loops obtained both from polar Kerr rotation measurements and magnetization measurements were found to be anomalous. These measurements showed that the magnetizations of the two phases are parallel to each other and perpendicular to the film surface, and that the signs of the Kerr rotation are opposite for the two phases. Further, the magnetizations of the two phases are not strongly coupled to one another. A simple model calculation which includes the anisotropy energy of each phase is able to reproduce the salient features of the experimental hysteresis loops.
