Single crystals of metallic dysprosium have been grown by the Bridgman method and their magnetic properties have been determined in different crystallographic directions of the hexagonal close-packed structure. Below the Neel point of 178.5 deg K the individual magnetic moments are aligned perpendicular to the c/sub o/ axis. The moments are aligned in an antiferromagnetic manner from 178.5 deg K down to 85 deg K and in a ferromagnetic manner below 85 deg K. Measurements with the field parallel and perpendicular to the c/sub o/ axis reveal magnetic anisotropy at all temperatures. Below 110 deg K magnetic anisotropy is also observed in the basal plane. The direction of easy magnetization is along an a/sub o/ axis. In the c/sub o/ direction the crystals are extremely hard'' magnetically, the magnetization curves being linear as in the case of a paramagnetic material. The saturation moments follow the T/sup 2/ law. (auth)
