Paramagnetism and Lattice Spacings of Some Cerium-Rich Cerium—Europium Alloys

Open publisher page 6 citations

Abstract

Paramagnetic susceptibility of cerium-rich cerium-europium alloys has been studied from 300° to 1050°K. These measurements indicate that the electronic structure of the localized 4f-electrons of europium atoms in solid solution with cerium is very much the same as in europium metal. This finding is supported by the lattice parameter measurements on these alloys at 298°K. The solubility limit of europium in cerium is found to be at 4.6 at.% europium at about 800°K.
