Abstract

This paper presents a comprehensive theoretical study of the intrinsic anomalous transport properties of magnetic cubic full Heusler compounds. The researchers demonstrate that several Heusler compounds exhibit significantly enhanced anomalous Hall effect (AHE) and anomalous Nernst effect (ANE) compared to previously reported materials. The study highlights the crucial role of symmetries, particularly mirror planes, in conjunction with magnetism, in achieving giant AHE and ANE. These findings are expected to be applicable to other linear responses dominated by intrinsic contributions.
