摘要：

The possible asymmetric phases in the Jahn-Teller crystal of KDy(MoO4)(2) are analyzed. Phases appearing upon a second-order phase transition from an orthorhombic D-2h(14) group with the unit cell volume doubling are described. It is shown that KDy(MoO4)(2) crystals are capable of featuring the Jahn-Teller pseudoeffect caused by the interaction between the electron states of dysprosium ions and the compressive (tensile) or shear deformations.
