Paramagnetism of Polycrystalline Gadolinium, Terbium, and Dysprosium Metals

Abstract
The paramagnetic susceptibilities of polycrystalline gadolinium, terbium, and dysprosium metals have been studied between 300–1500°K. The measurements are in good agreement with predictions which use the localized f-electron model of interacting rare-earth ions and the Van Vleck theory of paramagnetism. Departures from the Van Vleck theory are attributed to paramagnetism of conduction electrons. An approximate value of this contribution has been calculated for dysprosium.
