Abstract

AbstractOn the basis of the phenomenological theory of phase transitions the structural mechanism of ordering of octahedral cations of the type 1:3 in spinels is studied. With the help of the basic functions of the active six‐dimensional irreducible representations of the group Fd3m the structure of the ordered phase is deduced theoretically from the non‐ordered phase. The qualitative pictures of possible displacements of atoms near the temperature of the phase transition are given. The existence of isostructural modifications of the ordered structure is predicted.
