Deformations in the Crystal Structures of Anti-ferromagnetic Compounds

Abstract

IT has been shown that slight deformations occur in the crystal structures of various oxides of the iron group. B. Ruhemann1 has found that there is a very slight change in the crystal structure of MnO near 120° K. Rooksby2 and Tombs and Rooksby3 have reported that the face-centred, cubic arrangements in MnO, FeO, CoO and NiO show changes to tetragonal or rhombohedral symmetry upon cooling through a transition temperature.
