The magnetic susceptibility of single-crystal dysprosium-yttrium alloys was measured in the basal plane and along the hexagonal axis. It is shown that the susceptibility of these alloys obeys the Curie-Weiss law, the effective magnetic moments along the different directions are equal, and the paramagnetic Curie temperatures are different. The difference between the paramagnetic Curie temperatures in the basal plane and along the hexagonal axis does not depend on the dysprosium concentration in the alloys. This, as revealed by comparison with the theoretical models of magnetic anisotropy demonstrates that the magnetic anisotropy of dysprosium-yttrium alloys is of the one-ion type.
