Abstract

Three-dimensional neutron depolarization experiments have been performed on RCrO₄ (R=Y, Er, Tm, Yb) powder samples in order to gain insight into their magnetic domain structure in the submicrometer range. The temperature evolution of both the average domain size and the net magnetization of each compound has been studied for different applied magnetic fields. The largest average domain size at zero external magnetic field was found in YbCrO₄. The effect of an applied magnetic field on the magnetic domain structure is relatively small in ErCrO₄ and TmCrO₄, when compared to YCrO₄ and YbCrO₄ where the average domain size even surpasses the average particle size determined by Scanning Electron Microscopy studies.
