In this paper we have taken the Langbeinite family ? ? + 2 3 2 2 4 3 A M so ? ? of crystals with A = NH4, K, Rb, Cs, Ti and M = Mg, Ca, Mn, Fe, Co, Ni, Zn and Cd. The Langbeinite family of crystals which is exhibiting different higher order physical properties at various phase transition temperatures. Here we calculated ferromagnetoelectric (aev2) domain pairs of the crystal at different phase transition temperatures with the help of group theoretical methods of studying the effect of symmetry on some physical properties.
