Powder synthesis and crystal growth of Y2V2O7 under high pressure and its physical properties
Y2V2O7 with pyrochlore structure has been synthesized under a high pressure of 5 GPa at 1200 °C. The crystal structure has been determined by Rietveld analysis of the X-ray diffraction data. The structure is cubic with a=10.0143(8) Å and can be described by the space group F d -3 m (no. 227). Scanni...

description | Y2V2O7 with pyrochlore structure has been synthesized under a high pressure of 5 GPa at 1200 °C. The crystal structure has been determined by Rietveld analysis of the X-ray diffraction data. The structure is cubic with a=10.0143(8) Å and can be described by the space group F d -3 m (no. 227). Scanning electron microscopy data suggest the efficiency of the grain growth method for single crystal growth of Y2V2O7 under high pressure and high temperature conditions. Magnetic susceptibility data conforming to the Curie-Weiss law in the range 150-300 K with an effective moment peff of 1.76μB/V4+ ion and θ=+68 K indicates the predominance of ferromagnetic interactions. © 2007 Elsevier B.V.
