Abstract	We report the growth and the characterization of single crystals of the S=1/2 spin-dimer compound Pb2V3O9. 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*α(H−Hc1)1/φ, with φ =(2.00±0.04).
