چکیده

Theoretical modeling of the magnetic properties Fe 3 O 4 -Fe 3-x Ti x composites obtained by sol-gel method with subsequent hydrothermal treatment has been carried out. The magnetization reversal fields and number particles in different states an ensemble two-phase infinitely thin boundary between phases a characteristic size varying range from 30 to 80 nm were calculated using "magnetic rectangles" method. Hysteresis characteristics chemically inhomogeneous magnetostatically interacting obtained, consistent experimental data. Keywords: Composites, granulometry, micromagnetism, particles, magnetostatic interaction.

Synthesis and Characterization of Tb[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O and Eu[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
