Spin order and dynamics in the topological rare-earth germanide
semimetals
The $RE$Al(Si,Ge) ($RE$ = rare earth) family, known to break both the inversion- and time-reversal symmetries, represents one of the most suitable platforms for investigating the interplay between correlated-electron phenomena and topologically nontrivial bands. Here, we report on systematic magnetic, transport, and muon-spin rotation and relaxation ($\mu$SR) measurements on (Nd,Sm)AlGe …
