Effect of composition and thermal treatment on the properties and microstructure of Co–SiO2 films

Russian Physics Journal Aims and scope

The effect of various physical factors (chemical composition, temperature, and thermal treatment) on the macroscopic properties of Co–SiO2 film composites produced by ion-plasma sputtering of mosaic targets has been investigated. The microstructure parameters have been estimated indirectly by analyzing the magnetization curves and the temperature dependence of magnetization. It has been concluded that the model of homogeneous noninteracting superparamagnetic particles of hexagonal Co is applicable for describing the magnetic properties of the film composites under study over a rather wide range of compositions.
