Abstract
Low-temperature heat-capacity measurements on erbium oxide show an antiferromagnetic transition at 3.3 K, which is corroborated by magnetic-susceptibility data. Entropy calculations indicate that the magnetic ordering is associated with the ground-state doublet of ions located at one of their two nonequivalent sites in the cubic crystal.
