Abstract

- Hall resistivity ( ρH) studies confirm that the Curie temperature (Tc) can be varied reproducibly between 374 K and 368 K by suitably annealing the alloy at 250 °C and 300 °C respectively. This is explained as being due to changes in compositional short‐range‐order. The calculated magnetic susceptibility, obtained from the temperature dependence of ρH, shows a strong fluctuation contribution described by (T−Tc)−γ, with γ=1.54±0.04 in both cases. A significant contribution to the temperature dependence of the ohmic resistivity, which is also uneffected by the annealing conditions, is found to be of magnetic origin.
