Polyhedral distortions and unusual magnetic order in spinel FeMn${}_2$O${}_4$

Qiang Zhang, Wei Tian, Roshan K. Nepal +4

Spinel compounds AB${}_2$X${}_4$ consist of both tetrahedral (AX${}_4$) and octahedral (BX${}_6$) environments with the former forming a diamond lattice and the latter a geometrica…
