资源简介：
CsCu3DyTe4 was prepared by reacting copper, dysprosium, and tellurium with cesium azide at 850 °C in a fused silica ampule. This new telluride crystallizes in the monoclinic space group C2/m with lattice dimensions of a = 16.462(4) Å, b = 4.434(1) Å, c = 8. 881(2) Å, β = 108.609(12)° with Z = 2. Its crystal structure is dominated by ∞2{[Cu3DyTe4]}1– anionic layers separated by Cs+ cations. The copper cations are disordered over three different tetrahedral sites. The [DyTe6]9– polyhedra form infinite ∞1{[DyTe4]5–} chains. Magnetism studies conducted on this semiconductor suggest complex magnetic interactions between the Dy3+ cations with a strong deviation from Curie-type behavior at low temperatures below 40 K.
