Effect of Magnetic Pulse Treatment on Hexagonal Scandium-Substituted Ferrites with Multiferroic Properties

A study is performed of the effect magnetic pulse treatment has on the electromagnetic properties and crystal structure of high-temperature multiferroics (scandium-substituted barium hexaferrites). It is shown that a pulsed magnetic field enhances the covalence of the chemical bonds between Fe 3+ ions in fivefold coordination and non-centered octahedra as a result of the ordering of ions, cationic and anion vacancies, and additional displacement of Sc 3+ and Fe 3+ ions from the center of polyhedra.
