Wa. Vareka et al., TEMPERATURE-DEPENDENT RESISTIVITY IN RB3C60 - CONSTANT VOLUME VERSUS CONSTANT-PRESSURE, Physica. C, Superconductivity, 235, 1994, pp. 2507-2508
Under conditions of constant sample volume the normal state resistivit
y of rho of Rb3C60 has a temperature dependence rho similar to T, in s
harp contrast to rho similar to T-2 observed under conditions of const
ant sample pressure. Implications for the normal-state scattering mech
anism are discussed.
