Аннотация: Single crystals of Fe-substituted Cu(2)Mn(1-x)FexBO(5) ludwigites have been synthesized using flux technique (x = 0.2, 0.4, 0.5 - in the initial flux system). Structural properties of the synthesized compounds were studied by the single crystal and powder X-ray diffraction analysis. Obtained results were analyzed in the relationshiПоказать полностьюp with parent compound Cu2MnBO5. It was revealed that the type of monoclinic distortions of Fe-substituted ludwigites is different from the structure of Cu2MnBO5. The real cation composition and local structure of Cu(2)Mn(1-x)FexBO(5) ludwigites were studied using XANES and EXAFS techniques, respectively. Analysis of field and thermal dependencies of magnetization showed a high dependence of the magnetic properties of these ludwigites on x with changing the type of magnetic ordering.
