双腿自旋梯材料是研究低维磁性和高温超导性的理想模型之一,因此对它的探索是化学界的一个巨大挑战。本文报道了一种由CuO 4Cl 2八面体沿着[101]方向构筑的新型铜基双脚梯形化合物的合成。磁性测试结果表明,CdCu_2(SeO_3)_2Cl_2在T_(max)= 265 K处有一个宽峰,表明其基态为自旋单重态.对孤立双腿自旋梯模型的拟合结果表明,J ε/kB = 429 K,J ε/kB = 21 K,从而得到了一个大的自旋能隙,约为409 K.
The exploration of two-leg spin-ladder materials is a great challenge to the chemical community since it is one of the most ideal models for the study of low-dimensional magnetism and high-Tc superconductivity. Herein, we report on a successful synthesis of a new Cu2+-based two-leg ladder compound constructed by CuO4Cl2 octahedra along the [101] direction. The magnetic results exhibit a broad peak at Tmax ∼ 265 K, and suggest that CdCu2(SeO3)2Cl2 has a spin singlet ground state. The fitting of the isolated two-leg spin-ladder model shows J⊥/kB = 429 K and J‖/kB = 21 K, leading to a large spin gap of ∼409 K.
