Preparation, Structural and Magnetic Characterization of the BaTi(1-x)MnxO3 System

Abstract

The BaTiO3 is one of the most studied ferroelectric materials mostly due to its great potential for technological applications. Recently, other properties have been explored in BaTiO3, such as photoluminescence, photoacoustic and magnetism. These characteristics are mainly found when replacing the Ba and Ti ions by other transition metals or rare earths ions. The solid state reaction technique was used to prepare solid solutions of BaTi(1-x)MnxO3, in which the precursors BaCO3, TiO2 e MnO2 were weighed according to desired stoichiometry, for x between (0.001 ≤ x ≤ 0.1) and placed in the mill for 24 hours. Then, the obtained solid solution was calcined at a temperature of 1200 ° C for 1 hour. After calcination, the solid solution BaTi(1-x)MnxO3, were analyzed by X-ray diffraction, scanning electron microscope and by a magnetometer vibrating sample to verify the existence of magnetic properties. The results presented in this work are satisfactory, where we obtained a multiferroic material.
