In this work structural studies of BaFe 12 O 19 /Al 2 O 3 /Si 3 N 4 thin films with different thicknesses of aluminum oxide and silicon nitride are represented. It is shown that barium hexaferrite crystallizes on the amorphous surface of aluminum oxide with spontaneously formed (00l) uniaxial texture. Microstructural differences in BaFe 12 O 19 films were observed with varying of the thickness of amorphous sublayers, which is explained by the effect of mechanical stress.
