Résumé

Extensive magnetoresistivity experiments in large temperature (30 mK < T < 80 K) and field (H < 20 T) ranges are reported. At high temperatures (T > 4 K), the magnetoresistivity obeys a scaling law in H/H* with one temperature adjustable parameter H*( T). However no simple relation can be found between magnetoresistivity and magnetization. At low temperatures the A(H) T 2 terms of the resistivity are strongly field dependent although the specific heat of the normal phase is field independent. It is proposed that the field variation of A (H) reflects the strong field dependence of the direct interactions between quasi particles. The low temperature magnetoresistivity data are connected with the unusual superconducting properties of UBe 13 (specific heat and thermal conductivity).
