Characterization of W-type hexaferrite thin films prepared by chemical solution deposition

Thin films of W-type hexaferrite were grown on SrTiO3(111) single crystals using the chemical solution deposition method and metalorganic precursor solutions prepared modified Pechini method. The synthesis single-phase materials required optimizing initial stoichiometry crystallization conditions. results showed that a concurrent excess alkaline earth metal deficiency in divalent ion (Zn2+, Co2+) favors pure W hexaferrites. This off-stoichiometry suppressed formation an exceedingly stable spinel phase at pyrolysis temperatures. epitaxial nature thin films, expressed as orientation relation (00l)W || (111)SrTiO3 [110]W [112¯]SrTiO3 hence pronounced anisotropy their magnetic properties well established by three dimensional x-ray diffraction texture analysis magnetization measurements, respectively enabled to identify temperature interval which characteristic spin reorientation transition occurs for specific degree cobalt substitution.
