dc.description.abstractThe polycrystalline samples of TmxY2-xO3 (x = 0.1, 0.2, 0.4, 0.6, 1, 1.4, 1.8) were obtained by ceramic technology. X-ray diffraction data were collected and the crystal structures were refined by the Rietveld method, A random distribution of Tm3+ ions over two cationic sites, 8b and 24d, in the space group Ia (3) over bar was found. Magnetic susceptibility measurements of all samples were done using a SQUID susceptometer in a temperature range 4 K LT T LT 290 K, Above 90 K a Curie-Weiss law was observed, while below 90 K the inverse magnetic susceptibility deviates from linearity due to the crystal-held influence. Deduced effective magnetic moments are close to the free ion values. In the whole temperature range the susceptibility data were fitted in accordance with the axial symmetry approximation of the crystal field and corresponding values of the crystal-field energy levels were deduced.
