Résumé

We report measurements of the electrical resistivity of Ni1-xMnx alloy as a function of Mn concentration (0.05 < x < 0.33) and temperature (T = 4.2, 77 and 295 K). Contrary to the spontaneous magnetization which seems to vanish at a critical concentration xc ≈ 0.24, no anomaly is seen in the resistivity curves at any x. The residual resistivity per at% Mn increases monotoneously with x from ≈ 0.75 μΩcm for x → 0 to ≈ 3.2 μΩcm for x = 0.33. This is interpreted in the framework of a two-current like model in which mixing mechanism is produced by spin-glass disorder.
