The normal-state transport properties of alkali-metal-doped fullerene crystals are explored. The Hall effect has been measured in KxC60 from room temperature to Tc. The electrical resistivity ρ for K3C60 and Rb3C60 has been measured over a wide temperature range (20-650 K), and notable differences are observed for the materials at both low and high temperatures. The electrical resistivity of Rb3C60 has been measured in hydrostatic pressures up to 9 kbar. The resistivity is highly pressure sensitive. The transport results give an insight into the normal-state conduction mechanism and thus have consequences for the superconductivity mechanism.
