Beschreibungen/Notizen

• The magnetic phase transition in the KDy(WO 4) 2 single crystal has been first studied using the temperature dependence of the specific heat in a magnetic field. The ordering temperature of the Dy 3+ sublattice was established to be T N = 0.60 ± 0.02 K. The specific heat data are indicative of the antiferromagnetic character of Dy 3+ ions' interactions in the ac plane. The value of the effective interaction parameter J k was estimated. A part of the entropy is shown to be released at and above the transition temperature only. The temperature dependence of the specific heat above and below T N is discussed in the frameworks of the theoretical 2D and 3D Ising and XY models.
