Hexaferrite multiferroics: from bulk to thick films
Abstract
<jats:title>Abstract</jats:title><jats:p>We report studies of the structural and microstructural properties of Sr<jats:sub>3</jats:sub>Co<jats:sub>2</jats:sub>Fe<jats:sub>24</jats:sub>O<jats:sub>41</jats:sub> in bulk form and as thick films. The precursor powders for the bulk form were prepared following the sol-gel auto-combustion method. The prepared pellets were synthesized at 1200 °C to produce Sr<jats:sub>3</jats:sub>Co<jats:sub>2</jats:sub>Fe<jats:sub>24</jats:sub>O<jats:sub>41</jats:sub>. The XRD spectra of the bulks showed the characteristic peaks corresponding to the Z-type hexaferrite structure as a main phase and second phases of CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub> and Sr<jats:sub>3</jats:sub>Fe<jats:sub>2</jats:sub>O<jats:sub>7-x</jats:sub>. The microstructure analysis of the cross-section of the bulk pellets revealed a hexagonal sheet structure. Large areas were observed of packages of hexagonal sheets where the separate hexagonal particles were ordered along the <jats:italic>c</jats:italic> axis. Sr<jats:sub>3</jats:sub>Co<jats:sub>2</jats:sub>Fe<jats:sub>24</jats:sub>O<jats:sub>41</jats:sub> thick films were deposited from a suspension containing the Sr<jats:sub>3</jats:sub>Co<jats:sub>2</jats:sub>Fe<jats:sub>24</jats:sub>O<jats:sub>41</jats:sub> powder. The microstructural analysis of the thick films showed that the particles had the perfect hexagonal shape typical for hexaferrites.</jats:p>
