Magnetic Phase Transition in Nickel-Rich Nickel-Copper Alloys

並列摘要


The electrical resistivity, ρ, of a set of nickel-copper alloys has been studied between 300°K and 700°K. Our data show that each of the ρ vs. T curves exhibits a well-defined knee in the critical region of the magnetic phase transition; besides, the temperature dependent part of the electrical resistivity follows a T^(1.74±0.05) variation in the ferromagnetic region and increases more slowly than T in the paramagnetic region. The concentration dependence of the Curie temperatures of these Ni-Cu alloys has been determined from (dρ/dT) vs. T analysis. It is demonstrated that the dρ/dT method and the kink-point method give identical results.
