摘要：

The new quasi-one-dimensional spin gap compound BaCu2V2O8 was studied by means of magnetic susceptibility and heat capacity measurements on a powder sample. The magnetic susceptibility was well reproduced by alternating antiferromagnetic chain model with J(1)=260 K and J(2)=52 K, which result in a large spin gap of about 230 K. It is suggested that the J(1) and J(2) are ascribable to interactions along the Cu-O-V-O-Cu path and the Cu-O-Cu path, respectively.
