摘要：

We have measured the temperature-dependent electrical resistivity rho of polymerized KC60 from 410 to 1.9 K. rho(T) shows evidence for a metal-to-semiconductor phase transition near 50 K, and increases dramatically above 400 K. Between 400 and 50 K, rho is metal-like, decreasing smoothly with decreasing temperature. Under applied hydrostatic pressure, rho 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.
