Abstract

The orthorhombic one-dimensional polymer phase of Rb1C60 is proposed to be a Mott-Hubbard insulator, having three-dimensional electronic states, on the border of the metal-insulator transition at ambient pressure. That is confirmed from the transition temperature TN vs pressure phase diagram, which was obtained on the basis of the pressure dependence of TN by electron paramagnetic resonance (EPR), together with the electrical resistivity data under pressure reported by Khazeni et al. [Phys. Rev. B56, 6627-6630 (1997)]. The EPR linewidth can be understood from the Elliott mechanism viewpoint.
