Аннотация: Abstract: The effect Ме3+ (Al, Y, Sc, Fe, and Mn) cations on the structural properties and state of a zirconium dioxide surface layer is investigated. The thermal stability of the Ме3+ solid solutions based on a metastable zirconium dioxide modification is established via X-ray diffraction analysis. It is shown using X‑ray photoeleПоказать полностьюctron spectroscopy that the distribution of surface–volume cationic modifier is determined by the type of cation. In Al-, Fe-, and Mn-ZrO2 systems, modifiers are mainly distributed over a surface; in Y and Sc-ZrО2, modifiers are distributed uniformly. The nature of the cation distribution affects the thermal stability of the solid solutions formed. © 2018, Pleiades Publishing, Ltd. Near the Curie temperature TC = 30.3 K, the temperature dependences of the magnetization and heat capacity of a single-crystal ferromagnet PbMnBO4 in the magnetic fields of 1, 3, 10 and 30 kOe are studied. In the strong magnetic fields, both the magnetic
