A Theoretical Evaluation of Magneto-Transport Properties like Electrical Resistivity, Hall Resistivity, Hall Coefficient and Hall Angle of Some Heavy- Fermion Superconductors

In-filled CoSb3 skutterudites (InzCo4Sb12) were prepared and the filling effects on the thermoelectric and transport properties were examined. Seebeck coefficient and Hall coefficient confirmed that all the samples showed n-type conductivity. Temperature dependence of the electrical resistivity suggested that InzCo4Sb12 is a highly degenerate semiconducting material. The thermal conductivity was considerably reduced by In filling and the lattice contribution was dominant.

Heavy Fermion Superconductors

We present and analyze measurements of the electrical resistivity, the dc- and ac-susceptibility and the specific-heat of the quasi-binary alloy U ( Pd 1− x Ni x )2 Al 3 in the temperature range from 0.3K to 300K. All investigated properties indicate a continuous change from UPd 2 Al 3 to UNi 2 Al 3, with the exception of superconductivity, which dissappears for 0.12 ≤ x ≤ 0.95. The results stress the importance of crystal field effects.

High Seebeck Coefficient

ABSTRACTWe report transport properties of polycrystalline TMGa3(TM = Fe and Ru) compounds in the temperature range 313K<T<973K. These compounds exhibit semiconductorlike behavior with relatively high Seebeck coefficient, electrical resistivity, and Hall carrier concentrations at room temperature in the range of 1017- 1018cm−3. Seebeck coefficient measurements reveal that FeGa3isn-type material, while the Seebeck coefficient of RuGa3changes signs rapidly from large positive values to large negative values around 450K. The thermal conductivity of these compounds is estimated to be 3.5Wm−1K−1at room temperature and decreased to 2.5Wm−1K−1for FeGa3and 2.0Wm−1K−1for RuGa3at high temperature. The resulting thermoelectric figure of merit,ZT, at 945K for RuGa3reaches 0.18.
