Hexaferrites, magnetic iron-containing oxides, are superior materials with respect to the large magnetoelectric effect at elevated temperatures, coming from their frustrated noncollinear magnetic structures. Common in forms of ceramics, hexaferrites are only rarely developed in forms of crystals or thin layers. Latter successfully grown predominantly with c-axis oriented along the film normal, which is inconvenient for applications. Their magnetoelectric properties can be stilted or further enhanced by substitutions within their crystallographic structure, subsequently altering their magnetic structure and anisotropy. In the presented study this enhancement of magnetic structure was explored by preparation of potentially magnetoelectric M-type hexaferrite in thin film form with various Sc doping and different orientations and the ensuing measurements of magnetic properties. The Fe positions in the M-type SrFe12O19 are partially substituted by Sc atoms causing a noncollinear conical magnetic structure to form in place of the original collinear magnetic structure. The thin film samples of SrFe12-xScxO19 were prepared by chemical solution deposition method on Al2O3 single-crystal substrate. The measured temperature-dependent magnetic anisotropy is similar to that of magnetoelectric ceramics with x(Sc)=1.5, which suggests a possibility to observe a magnetoelectric effect in the prepared films.
