Аннотация: A magnetic resonance method is applied to the investigation of a number of isostructural diamagnetic compounds ABO3 (A = Sc, Lu, In) with small additions of Cr3+ ions (S = 3/2) sufficient to observe single-ion spectra. It is shown that the resonance spectra for isolated Cr3+ ions can be described to a good accuracy by the ordinary axial spin Hamiltonian for 3d ions in octahedral oxygen environment. The parameters of the spin Hamiltonian are determined. It is established that Cr3+ ions in these crystals are characterized by easy-axis-type anisotropy.

Аннотация: The Mossbauer effect in the Fe1 - xVxBO3 solid solutions has been measured at 130 and 300 K. The Fe0.05V0.95BO3 composition was studied in the interval 4.2-300 K. The experimental data obtained are described in terms of the model of a dilute magnetic insulator in which atoms of the first coordination sphere provide a major contribution to the hyperfine field at iron nucleus sites. It was found that, at low temperatures, the field H-hf is generated primarily by the iron ion itself and depends only weakly on substitution. The hyperfine interaction parameters in the discrete configuration series 6Fe, 5Fe1V, 4Fe2V, 3Fe3V, and 2Fe4V were determined. The magnitude of the isomer shift suggests that iron in the crystal resides in the trivalent state. (C) 2004 MAIK "Nauka/Interperiodica".

Аннотация: The room-temperature EXAFS measurements have been made on FeBO3 and VBO3, as well as on Fe1-xVxBO3 series with concentration x=0.13,0.3, and 0.95. The first-shell Me-O bond lengths deduced from EXAFS have shown a compositional independence. It has been found that Fe1-xVxBO3 forms solid solutions with random distribution of Fe3+ and V3+ ions.
