NORMAL-STATE TRANSPORT-PROPERTIES OF FULLERENE SUPERCONDUCTORS

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 T(c). The electrical resistivity rho for K3C60 an d Rb3C60 has been measured over a wide temperature range (20-650 K), a nd notable differences are observed for the materials at both low and high temperatures. The electrical resistivity of Rb3C60 has been measu red in hydrostatic pressures up to 9 kbar. The resistivity is highly p ressure sensitive. The transport results give an insight into the norm al-state conduction mechanism and thus have consequences for the super conductivity mechanism.
