Resumo
The BiFeO3/Sr0.6Ba0.4Nb2O6 two-layer heterostructure have been sputtered onto a (001)MgO single-crystal substrate by high-frequency sputtering in an oxygen atmosphere. The layers of the heterostructure were obtained epitaxially, where the lower Sr0.6Ba0.4Nb2O6 layer was obtained with the formation of two types of orientational domains, and the upper BiFeO3 layer was obtained in the full parallel orientation ratio with the substrate. According to atomic force microscopy the surface of the heterostructure is a block structure with a low value of the root-mean-square surface roughness. The study of magnetic force microscopy of the heterostructure surface showed the presence of a response at the grain boundaries associated only with the BiFeO3 layer. The causes of the revealed effects are discussed.
