通过在温度、压力和磁场控制下的电阻测量，研究了磁场对准二维层状有机导体kappa-（BEDT-TTF）（2）Cu[N（CN）（2）]Cl中Mott转变附近的高关联金属的影响.结果表明，Mott转变附近的边缘金属相是敏感的一级场致局域化转变，从理论上预测。本研究结果的热力学考虑给出了一个概念性的压力场相图的莫特转变在低温下。
We investigated the effect of magnetic field on the highly correlated metal near the Mott transition in the quasi-two-dimensional layered organic conductor, kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Cl, by the resistance measurements under control of temperature, pressure, and magnetic field. It was demonstrated that the marginal metallic phase near the Mott transition is susceptible to the field-induced localization transition of the first order, as was predicted theoretically. The thermodynamic consideration of the present results gives a conceptual pressure-field phase diagram of the Mott transition at low temperatures.
