Abstract
Investigations of magnetic and spontaneous birefringence properties of a KDy(MoO4)(2) crystal under the Jahn-Teller phase transformation rev eal some features indicating the existence of two spontaneous phase tr ansitions at temperatures close to 14.3 and 11.0 K. The characteristic changes in birefringence in these transitions suggest that the crysta l of KDy molybdate has a modulated incommensurate lattice structure in the temperature range from 11.0 to 14.3 K.
