Аннотация

Single crystals of Fe-substituted Cu₂Mn_1-xFe_xBO₅ 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 relationship 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 Cu₂Mn_1-xFe_xBO₅ 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.
