Abstract

Normal-state measurements of RNi2B2C are reported. The resistivity of polycrystalline RNi2B2C (R=Y, Ho and La) has been measured to 600K. All three compounds have a linear resistivity above 300K but the superconducting compounds show a distinct curvature below this temperature. The thermopower and static magnetic susceptibility have been measured for the same samples to 300-400K. Single crystals of the superconducting compounds RNi2B2C (R=Lu, Er, Ho) have been polished into geometric bars for direct measurement of the in-plane resistivity (ρa) and the c-axis resistivity (ρc). The in-plane resistivity of all three compounds is parallel and the effect of spin-disorder scattering is discussed. The resistivity shows very little anisotropy despite the layered structure of these materials.
