The magnetic structure of a single crystal of the rare earth random alloy Ho 50% Er 50% has been investigated by elastic neutron diffraction measurements in the temperature range 120-10 K. Three distinct magnetic phases are indentified below the Néel temperature of 104 K. The high- temperature phase observed between 104 K and 47.5 K is a binary magnetic structure where the holmium and erbium moments belong to different modulated c -axis spirals. The intermediate-temperature phase between 47.5 K and 35 K is a simple basal plane spiral. Below 35 K, the measurements suggest a ferrimagnetic stucture in which the holmium and erbium moments are indistinguishable and form a conical spiral with a half-cone angle of 20°.
