The resistivity (ρ) at temperatures below 4.2 K of palladium alloys with 2 to 6 at% nickel has been measured and fitted to the expression ρ - ρ0 = AT n . The behaviour of A clearly indicates the critical concentration for the para- to ferromagnetic transition at 2.32 ± 0.03 at% nickel. Well away from this composition n is close to 2.0, but decreases on approaching it from either side.
