摘要：

The magnetic properties of Na5RbCu4(AsO4)(4)Cl-2 are reported. The material has a layered structure comprised of square Cu4O4 tetramers. The Cu ions are divalent and the system behaves as a low-dimensional S=1/2 antiferromagnet. Spin exchange in Na5RbCu4(AsO4)(4)Cl-2 appears to be quasi-two-dimensional and nonfrustrated. Measurements of the bulk magnetic susceptibility and heat capacity are consistent with low-dimensional magnetism. The compound has an interesting, low-entropy, magnetic transition at T=17 K.
