AB  - Polycrystailline samples of the cubic SmxY2-xO3 solid solutions (x = 0 2, 0.5. 1 0, 1 4, 1.7 and 2.0) were prepared and analyzed by the XRD and magnetic susceptibility measurements. Random distribution of Sm3+ ions between 24d and 8b site was found. except for diluted samples (x = 0.2 and 0 5). where Sm3+ ions preferentially occupy 24d site. The susceptibility data was analyzed within 2-150 K range according to the second order perturbation (Van Vleck equation) The strength of exchange interactions was estimated from low-temperature susceptibility within 2-20 K (effective g-value and Curie-Weiss temperature) The effective g-value and the Curie-Weiss temperature theta for Sm2O3 were found to be 0.451 and -3.97 K, respectively (C) 2009 Elsevier B V.

AB  - The alpha-Fe(2)O(3)/SiO(2) nanocomposite containing 45 wt% of hematite was prepared by the sol-gel method followed by heating in air at 200 degrees C. The so-obtained composite of iron(III) nanoparticles dissolved in glassy silica matrix was investigated by X-ray powder diffraction (XRPD), transmission electron microscopy (TEM), and superconducting quantum interference device (SQUID) magnetometry. XRPD confirms the formation of a single-phase hematite sample, whereas TEM reveals spherical particles in a silica matrix with an average diameter of 10 nm. DC magnetization shows bifurcation of the zero-field-cooled (ZFC) and field-cooled (FC) branches up to the room temperature with a blocking temperature TB 65 K. Isothermal M( H) dependence displays significant hysteretic behaviour below TB, whereas the room temperature data were successfully fitted to a weighted Langevin function. The average particle size obtained from this fit is in agreement with the TEM findings. The small shift of the TB value with the magnetic field strength, narrowing of the hysteresis loop at low applied field, and the frequency dependence of the AC susceptibility data point to the presence of inter-particle interactions. The analysis of the results suggests that the system consists of single-domain nanoparticles with intermediate strength interactions. (c) 2008 Elsevier B.V. All rights reserved.
