Abstract
The electrical resistivity, magnetoresistance (MR) and upper critical field (Hc2) of single-crystal superconducting YbRh1.4Sn4.6 have been studied. The high-temperature resistivity shows a saturation effect while an anomalous T2 dependence is observed at low temperatures. The high-temperature resistivity is interpreted in terms of a parallel-resistor model in which high-temperature saturation occurs where the electron mean free path reaches a lower limit approximately equal to the interatomic spacing. It is concluded that the T2 dependence is not due to electron-electron scattering and a theoretical understanding still remains unresolved. From the critical field study the authors have estimated the normal specific heat coefficient to be gamma =11.7 mJ mol-1K-2. It is also concluded that the Yb ion is in the divalent state in YbRh1.4Sn4.6.
