Abstract:With a view to the proven multiferroic properties of the title representatives of the Y-type hexaferrites as single crystals we present here a comparative study of their microstructure and magnetic properties for powders. The polycrystalline materials of Ba0.5Sr1.5Zn2Fe12O22 (S1) and its doped with aluminium derivative Ba0.5Sr1.5Zn2Al0.08Fe11.92O22 (S2) were synthesized by two different techniques: citric-acid sol-gel auto-combustion and sonochemical co-precipitation. Their atomic-level structure determination… Show more
