Transition from heavy fermion metal to 16 K superconductor in single crystal YbxLu(1-x)Ni2B2C: transport studies Conference Paper

abstract

• YbNi 2 B 2 C has been found to be a heavy fermion metal with neither superconductivity nor magnetic order in contrast to the other members of the borocarbide family. LuNi 2 B 2 C is a superconductor with T c~ 16.3 K and no magnetic order. Transport studies on single crystal Yb x Lu (1-x) Ni 2 B 2 C show a systematic change from a heavy fermion system to a moderately high-temperature superconductor. A "giant" thermopower is observed for small x to x =1, i.e., in the transition region from a Kondo alloy to a heavy fermion metal. Measurements of H c2( T, x ) are also reported for x <0.15.
