Magnetic ordering of Dy3+ ion in low-dimensional CsDy(WO4)2 double tungstate

Abstract

Magnetic ordering of Dy3+ ion in low-dimensional magnet CsDy(WO4)2 has been first studied by means of measurements of the low temperature specific heat over a temperature range of 0.5-23K. The ordering temperature of the Dy3+ sublattice was established to be 1.34K. The experimental data indicate on the antiferromagnetic character of Dy3+ ions interactions. The magnetic behavior above and below Tn is discussed in the framework of different theoretical models.
