Abstract

We have measured the temperature-dependent electrical resistivity ρ of polymerized KC60 from 410 to 1.9 K. ρ(T) shows evidence for a metal-to-semiconductor phase transition near 50 K, and increases dramatically-ab decreasing temperature. Under applied hydrostatic pressure, ρ decreases, and the 50-K transition is suppressed. No anomalous magnetoresistance is observed up to 7 T, and we find no evidence of superconductivity above 1.9 K.
