- 論文の詳細を見る
From the resistivity and magnetic susceptibility measurements of polycrystalline Bi_xV_8O_<16> with 1.6<x<1.8, it was revealed for the first time that Bi_xV_8O_<16> with 1.72<x<1.8 exhibits a temperature-induced metal-insulator transition (MIT). A large hysteresis was observed in their Susceptibilities and resistivities as functions of temperature, indicating that t,he MIT is of the first order. The possibility of charge ordering between V^<3+> and V^<4+> has been discussed for the origin of the MIT in this system. In the insulating phase, Bi_xV_8O_<16> with 1.72<x<1.8 indicates another anomaly in the magnetic susceptibility, which may imply magnetic ordering below the anomaly temperature. We suggest that the physical properties of this system are controlled by multiple order parameters including charge, spin, and orbital quanta.
