Crystal structure, physicochemical, and sensory properties of solid solutions Bi[1-x]La[x]Fe[1-x]Co[x]O[3] (x = 0, 0.05, 0.1)

Abstract

For the first time, the synthesis was carried out and the physicochemical properties of solid solutions based on the multiferroic BiFeO[3] were studied. It was found that the samples were characterized by a rhombohedrally distorted perovskite structure. It was shown that a slight isovalent substitution of Bi{3+} ions by La{3+} ions and Fe{3+} ions by Co{3+} ions in BiFeO[3] (x < 0.10) leads to an increase in the specific magnetization. This can be attributed to structural distortions and causes weak ferromagnetism to occur. The studied samples are ptype semiconductors and have good sensory properties even without catalysts. It was found that the maximum values of the S response were obtained at temperatures close to the ferromagnetic Curie temperature, the value of which is consistent with the studies of electrical properties.
