Title: Possible Bose-Einstein condensate of magnons in single-crystalline Pb{sub 2}V{sub 3}O{sub 9}

Abstract

We report the growth and the characterization of single crystals of the S=1/2 spin-dimer compound Pb{sub 2}V{sub 3}O{sub 9}. Magnetic-susceptibility, torque magnetometry, heat-capacity, and muon-spin-relaxation measurements provide evidence for a field-induced Bose-Einstein condensate of magnons in this system. At low temperatures, the field-dependent phase boundary between the dimerized and the condensed state is well described by the expression T*propor to(H-H{sub c1}){sup 1/p}hi, with phi=(2.00+-0.04).
