Interconnection of structural and magnetic phase transition observed in single crystal CsEu sub(x)Dy sub(1-x)(MoO sub(4)) sub(2)

The Eu impurity effect on the magnetic properties in the region of the magnetic phase transition is studied in chain-layered low-symmetry Ising compound CsDy(MoO sub(4)) sub(2) having a structural phase transition of the Janh-Teller type. The dependence of the ordering temperature on Eu concentration is indicative of low magnetic dimension of CsDy(MoO sub(4)) sub(2). It is also shown that the impurity influences the features of the dynamic susceptibility related to the spin-phonon interaction.
