Hexaferrite multiferroics: from bulk to thick films

Journal of Physics: Conference Series, 2018
Abstract We report studies of the structural and microstructural properties of Sr3Co2Fe24O41 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 Sr3Co2Fe24O41.
