Mixed sesquioxides (Lu0.9Er0.1)(2)O-3 and (Lu0.9Yb0.1)(2)O-3 were prepared and analyzed by the XRD and magnetic susceptibility measurements. The samples crystallize in the space group 10 with a byxbyite structure type. The structure refinement have shown that Er3+ exclusively OCCUPY C-2 sites in (Lu0.9Er0.1)(2)O-3, while Yb3+ are preferentially distributed in C-3i sites in (Lu0.9Yb0.02O3. Magnetic susceptibility data in the whole 2-300 K temperature region was analyzed by the model based on perturbation theory. The mean energy gap between ground and some of the excited crystal field levels (E-i), and their effective magnetic numbers M-ieff were determined. The obtained energy levels are compared with theoretical values, and discussed in relation to the cation distribution. An analysis of paramagnetic temperature has shown absence of magnetic ion clustering. (c) 2007 Elsevier B.V. All rights reserved.
