Non-collinear magnetism and topological electronic structure in the half-Heusler compounds PrNiBi and PrPtBi

The half-Heusler XYZ compound exhibits a non-centrosymmetric cubic structure, crystallizing in the cubic C1_b crystal structure with the F\(\:\stackrel{-}{4}\)3m space group, where X and Y are transition metal or rare earth elements, while Z is a…
