Non-collinear magnetism contra frustration: Magnetic order and anisotropy in hexagonal MnPtGa

Gerhard H. Fecher, Roshnee Sahoo, Claudia Felser

MnPtGa is a hexagonal intermetallic compound with a rich variety of magnetic order. Its magnetic state is reported to range from collinear ferromagnetism, to non-collinear skyrmion…
