Physical Review B
We present the temperature dependence of the uniform susceptibility of spin-half quantum antiferromagnets on spatially anisotropic triangular-lattices, using high temperature series expansions. We consider a model with two exchange constants, J_1 and J_2 on a lattice that interpolates between the limits of a square-lattice (J_1=0), a triangular-lattice (J_2=J_1), and decoupled linear chains (J_2=0). In all cases, the susceptibility which has a Curie-Weiss behavior at high temperatures, rollsdoi:10.1103/physrevb.71.134422 fatcat:cyhyla36angkdkfnf73fd2xz5u
