Electronic structure of spin frustrated magnets: Mn${}_3$O${}_4$ spinel and postspinel

S. Hirai, Y. Goto, A. Wakatsuki +3

Mn${}_3$O${}_4$ is a spin frustrated magnet that adopts a tetragonally distorted spinel structure at ambient conditions and a CaMn${}_2$O${}_4$-type postspinel structure at high pressure.…
