Аннотация: Using the group-theoretical methods, the complete set of critical and noncritical order parameters arising at phase transitions in crystals with the O-h(5)- Fm3m space group has been obtained and analyzed. The mechanical and permutation representations have been constructed, and their composition for all the right systems of pointsПоказать полностьюof the O-h(5) h space group has been determined. Experimental data on structural phase transitions in ammonium cryolites and elpasolites have been considered.
