Abstract Electrical resistivity of high purity (99.99 + %) iron has been studied as a function of temperature from 300 to 1300 °K. It has been found that the resistivity decreases by about 2% going from α to γ iron. Such a large change has not been previously observed. The temperature dependence of the electrical resistivity of α and γ iron near the α → γ transition is not the same as has been reported in older investigations. The resistivity at the Curie temperature does not exhibit a sharp anomaly but changes gradually with temperature.
