CoV 2 O 6 has two structural forms: a low-temperature phase (γ-CoV 2 O 6 ) and a high-temperature one (α-CoV 2 O 6 ), separated by a structural transition which occurs at 953K. In this paper, we first report on large sized single crystals of γ-CoV 2 O 6 grown successfully by the flux method at a slow cooling rate. The quality of grown crystals is confirmed using XRD and EPMA techniques. Magnetic properties are investigated by means of susceptibility, magnetization, and heat capacity measurements. Our results confirm that γ-CoV 2 O 6 possesses a long-range antiferromagnetic ordering at ~6K, in which 1/3 magnetization plateau occurs at the critical field of ~2500Oe applied along the magnetic c-axis.
