| This paper presents the results of the study on structure and magnetic properties of the perovskite-type (BiFeO3 )x -(BaTiO3 ) 1 − x solid solutions. The samples differing in the chemical composition (x = 0.9, 0.8, and 0.7) were produced according to the conventional solid-state sintering method from the mixture of powders. Moreover, three different variants of the fabrication process differing in the temperatures and soaking time were applied. The results of X-ray diffraction (XRD), Mössbauer spectroscopy (MS), and vibrating sample magnetometry (VSM) were collected and compared for the set of the investigated materials. The structural transformation from rhombohedral to cubic symmetry was observed for the samples with x = 0.7. With increasing of BaTiO 3 concentration Mössbauer spectra become broadened re fl ecting various con fi gurations of atoms around 57 Fe probes. Moreover, gradual decreasing of the average hyper fi ne magnetic field and macroscopic magnetization were observed with x decreasing. |
