Electrical Resistivity of Chromium in the Vicinity of the Néel Temperature

Abstract

Previous work by other investigators has shown that a sharply cusped minimum occurs in the resistivity-temperature relationship for fully recrystallized chromium at the Néel temperature, i.e., 35°C. Plastic deformation, on the other hand, eliminates this minimum, and in addition gives rise to a pronounced change in the resistivity-temperature relationship over a wide range of temperatures centered about the Néel temperature. These results have been corroborated in the present paper. Furthermore, this behavior has been analyzed and interpreted in terms of the strong dependence of the Néel temperature on hydrostatic stresses which are thought to arise from the presence of dislocations in the deformed material.
