D. Rodic et al., THE RARE-EARTH ION DISTRIBUTION IN MIXED RARE EARTH-YTTRIUM SESQUIOXIDES, Journal of magnetism and magnetic materials, 144, 1995, pp. 1181-1182
In order to determine the rare earth ion distribution in RexY2-xO3 (Re
= Gd, Dy, Ho, Er), for 0 < x < 2, the X-ray diffraction and the magne
tic measurements were done. The preferential and the random distributi
ons of the magnetic ions over two crystallographic sites, depending on
Re3+ ion nature, and their clusterization were found.
