Essay

K2Cd2xMn2(1-x)(SO4)3 crystals were grown by Czochralsky and Bridgman standard technique. On the basis of the investigated optical and other physical properties the concentration-temperature phase diagram was constructed and isolated point was found. Existance of isolated point was analyzed on the basis of phenomenological approach. The paraelastic phase region was not observed between domains in the "forbidden" ferroelastic domain structure in Tl2Cd2(SO4)3 crystals. Phase transition with a change of symmetry 23 to 3 was found in Rb2Cd2(SO4)3 crystals.
