Abstract

The specific heat C(T) of the monoclinic RbDy(WO₄)₂ crystal has been studied at very low temperatures 0.2 ≤ T ≤ 1.9 K and in magnetic fields 0 ≤ H ≤ 0.38 T. The Neel temperature was shown to be equal to T_N = 0.818 ± 0.005 K. The experimental value of the effective exchange parameter was obtained to be equal to J/k = -0.798 K. The C(T) dependence below Neel temperature (0.5 T_N < T < 0.99T_N) is well described by 2D Ising model, whereas in the temperature region close above T_N (1.01T_N < T < 2T_N) it can be described by neither 2D, nor 3D Ising model. The experimental and theoretical H-T_N diagrams for field H ∥ a are in a reasonable agreement for simple quadratic lattice.
