Exploration of the spin-phonon coupling in the noncollinear antiferromagnetic antiperovskite Mn${}_3$NiN

L. Florez-Gomez, W. Ibarra-Hernandez, A. C. Garcia-Castro

Antiferromagnetic antiperovskites, of the form Mn${}_{3}B$N ($B$ = Ni, Cu, Zn, Sn, Ir, and Pt), have shown an outstanding behavior in which, giant negative thermal expansion and chiral…
