The most significant effect - a first-order transition from the collinear ferrimagnetic to a canted state - is observed at about 40 T with H ll [001]. The transition is accompanied by a prominent magnetization jump as well as by step-wise anomalies of the magnetoelastic properties. The volume of the crystal reduces by about 4 per mil, while the speed of transverse sound in the [001] direction increases by as much as 5 per mil. At higher temperatures, the anomalies gradually become smaller and less sharp, before they finally disappear at 50 K. The anisotropy constants of the Er sublattice and the molecular field thereon have been determined from the magnetization curves.
