Abstract (english): In this study scandium-doped barium hexaferrite thin-films intended for self-biased nonreciprocal devices are produced by means of the sol-gel method on alumina substrate. The scandium doping factor is varied between x = 0:025 and x = 0:4. X-ray diffraction analysis and the measured hysteresis curves are shown for both doped and undoped films. For broadband microwave characterization the thin-films are deposited on coplanar waveguides. In experiments the ferromagnetic resonance frequency is shown to be adjustable from 43:2 GHz to 27:1 GHz by increasing the scandium-doping level and nonreciprocal behavior is demonstrated.
