We report measurements of the bulk magnetic susceptibility, the EPR susceptibility, and the13C nuclear spin-lattice relaxation and paramagnetic shift in the normal state of K3C60.Many aspects of the results indicate that the conduction electron properties can be modeled by Fermi-liquid behavior in a narrow band. Some weak-temperature dependences are observed that deviate from simple metallic behavior and may reflect interactions in the system. The parameters we obtain from a nearly-free-electron analysis are in reasonable agreement with band structure calculations, photoemission experiments, and the superconducting-state parameters.
