Abstract
Ytterbium iron garnet (YbIG) is a cubic ferrimagnet having a compensation point Tcomp ≃ 6°K. We have undertaken precision magnetization measurements along [111] and [100] of a YbIG crystal in the temperature range 2°K < T < 30°K, with applied fields H up to 23 kG, in order to study the abrupt changes of the magnetization which occur in the H‐T region where the net Yb and Fe moments are not collinear. These jumps in the magnetic moment are at variance with the temperature‐independent magnetization in the canted phase predicted by models of isotropic ferrimagnets, and arise from the large aniso‐tropy in the Yb g‐factor and Yb‐Fe exchange. A recently derived phase diagram for anisotropic YbIG predicts first order phase transitions, corresponding to abrupt sub‐lattice reorientations while in the canted state, which accord well with the observed moment variations.
