| Description |
The quasi-two-dimensional antiferromagnet CsDy(MoO₄)₂ is studied by neutron diffraction and quasielastic neutron scattering. The crystal structure of two low-temperature phases (below 120 K and below 40 K) is determined. An approximate structure of the magnetically ordered phase (TN = 1.36 K) is proposed. In the ordered state the order-parameter critical exponent β = 0.17(0.01), the in-plane correlation length exponent ν = 0.94(0.07), and the staggered susceptibility critical index γ= 1.01(0.04) were determined. Comparing these results to the exact solution for a 2D Ising magnet we conclude that, although 2D behavior is apparent in CsDy(MoO₄)₂, there are deviations from the simple 2D Ising model. |
