摘要：

A neutronographic study is made of magnetic structure and spin‐orientational transitions in polycrystalline samples of the system BaCo2−xZnxFe16O27 (Co2−xZnxW). Along with this studies measurements of the macroscopic magnetic characteristics, X‐ray dilatometry, and DTA are performed. The diagram of the magnetic state is plotted in the coordinates: content‐temperature. The compounds with Zn2+ ion content, 0 ≦ x ≦ 1.6 exhibit the sequence of orientational phase transitions coneplane‐cone‐axis of easy magnitization when the temperature increases. The order of these transitions is determined and the role of Co2+ ions for creation of planar anisotropy in oxide ferrimagnetics with hexagonal structure is discussed.
