چکیده انگلیسی
High quality centimeter size single crystals of Bi(Cu1âxZnx)2PO6 (x=0%, 1%, 5%) have been successfully grown by the Travelling Solvent Floating Zone (TSFZ) technique. The crystals were grown with a rate of 1Â mm/h in a gas mixture of 20% O2 in Ar. Characterization of the single crystal samples by means of optical microscopy, X-ray powder diffraction, X-ray Laue diffraction, neutron diffraction and magnetization measurement are reported. The magnetic susceptibility Ïspin(T), measured from 2 to 300Â K, passes a broad maximum around 60Â K, followed by an exponential decrease towards lower T, and confirm the formation of a spin singlet ground state at low temperature. At low-temperature a paramagnetic Curie-like upturn quantitatively reflect the increasing Zn-doping level.
