Belous, O. V'yunov, O. Yanchevskii, A. Tovstolytkin, V. Golub] Bulk ceramic samples of (La0.7Sr0.3)(Mn1 − x Cux)O3 ± δ manganites are prepared by solid-state reactions. The unit-cell parameters and Mn-O bond distances in the manganites are determined using the Rietveld profile analysis method, and their magnetic properties are studied with the use of ferromagnetic resonance measurements. The results attest to the formation of solid solutions. Their lattice parameters follow Vegard's law. The way in which the saturation magnetization of the manganites varies with composition depends on x. For x ≤ 0.07, the saturation magnetization is a weak function of composition; for x > 0.07, it drops rapidly with increasing x. These results can be understood under the assumption that the only oxidation state of copper in (La0.7Sr0.3)(Mn1 − x Cux)O3 ± δ is 2+. Pleiades Publishing, Inc., 2006 Belous A.
