【 摘 要 】
Taking the noncollinear antiferromagnetic hexagonal Heusler compound Mn3Ge as a reference system, the contributions to linear response phenomena arising solely from the chiral coplanar and noncoplanar spin configurations are investigated. Orbital moments, x-ray absorption, and anomalous and spin Hall effects, as well as corresponding spin-orbit torques and Edelstein polarizations, are studied depending on a continuous variation of the polar angle relative to the kagome planes of corner-sharing triangles between the noncollinear antiferromagnetic and the ferromagnetic limits. By scaling the speed of light from the relativistic Dirac case to the nonrelativistic limit the chirality-induced or topological contributions can be identified by suppressing the spin-orbit coupling.
