Properties of barium hexaferrite thick films deposited by electron beam evaporation

This paper presents results obtained on barium ferrite thick films prepared by electron beam evaporation. First of all, we have looked at the influence of substrate temperature on the films properties. Then, we have fixed the substrate temperature to 700 °C and the effects of films thickness on the different properties has been investigated. Indeed for a substrate temperature of 700 °C we have observed that the layers are crystallized in the BaM phase with in-plane preferential orientation. However, a secondary non magnetic phase (BaFe2O4), which can modify the magnetic properties, appears on some layers.
