Abstract
Dysprosium is ferromagnetic below 85°K, antiferromagnetic between 85 and 179°K, and paramagnetic above 179°K. The spontaneous magnetic moment lies always in the basal plane, and there is anisotropy in this plane below 110°K. In the present paper it is shown that the magnetic properties can be interpreted in terms of a two-sublattice model and a phenomenological theory similar to a theory proposed by Néel. Detailed agreement for the magnetization curves in the ferromagnetic and antiferromagnetic regions is obtained.
