Flux growth and magnetic properties of FeVO4 single crystals

摘要

FeVO4 (I) single crystals are grown by the flux method using V2O5 as the self-flux. The grown Crystals exhibit a characteristic morphology with natural facets. The quality of the crystals is confirmed by X-ray diffraction and EPMA techniques. Magnetic properties are investigated by means of magnetic susceptibility, magnetization, and heat capacity measurements. Two magnetic phase transitions are observed at similar to 13 and similar to 20K. Such unusual magnetic behaviors are suggested to originate from two different Fe ligand environments of octahedral FeO6 and trigonal bipyramidal FeO5 in a six-column doubly bent chain., (C) 2008 Elsevier Inc.
