Abstract
Polycrystalline samples of the quasi-one-dimensional, spin 1/2 chain compound BaCu2V2O8 and the zinc doped Ba(Cu1-xZnx)2V2O8 (x = 0.05, 0.1, 0.15, 0.2, 0.3 and 0.4), were synthesized using the solid state reaction method. Small size single crystals (~1.5mm3) were grown using the vertical Bridgman-Stockbarger method and the slow cooling method. Crystal structure and magnetic properties were characterized using powder x-ray diffraction and superconducting Quantum Interference Device (SQUID), respectively. Magnetic susceptibility measurements on the polycrytalline samples suggested that the magnetic behavior of this compound was best described by an isolated dimer model.The effect of substituting zinc for copper on the spin gap (^) showed that A was weakly dependent on x, which confirmed that the isolated dimer model was valid in order to explain the origin of the spin gap in this system.
