Specific heat and resistivity of iron near its Curie point

Abstract

The specific heat and the temperature derivative of electrical resistivity of Fe have been measured simultaneously using an ac technique. The results for Fe demonstrate that the magnetic specific heat and the temperature derivative of the magnetic contribution to the resistivity are proportional both above and below the Curie point. The critical exponents are found to be $\alpha ={\alpha }^{\prime }=-0.120\mathrm{}\pm 0.01$.
