Electronic Structures and Magnetic Properties of Co2CrAl Films

다국어 초록 (Multilingual Abstract)

In this study, Co2CrAl Heusler alloy (HA) films with significantly different structural orders were fabricated and the in fluence of atomic disorder on various physical properties was investigated. We found that the lattice constant of the films gradually increased as the structural disorder increased. We also showed that the ordered Co2CrAl HA films were ferromagnetically ordered with a Curie temperature close to that of the bulk sample. The structural disorder causes a reduction in the saturation magnetization and the decrease in the Curie temperature. As the structural order was increased, the main peak of the Co L3-edge spectrum shifted to a higher energy. The observed experimental results were analyzed in connection with changes in the atomic and the electronic structures.
