Low temperature magnetoresistivity of UBe13

Abstract
Very low temperature magnetoresistivity experiments exhibit a simple quadratic Tc dependence of the resistivity just above the superconducting transition temperature Tc. Extrapolated residual resistivity depends strongly on the magnetic field. For 12 T ≽ H ≽ 4 T, the magnetoresistivity can be fitted by : p (T,H) = ρ0 (H) + A(H)T2 po and A following respectively √H and H variations. Emphasis has been given on the duality between light and heavy particles
