Improvement of magnetic properties through the synthesis of ceramic materials with various weight ratios of BaTiO, BiFeO3, and BaFe12O19 with sol-gel method

Abstract

Electronic devices designed with multiferroic materials comprising both electrical and magnetic properties are needed for significant memory storage. Several studies have been carried out on multiferroic materials based on BaTiO3, BiFeO3, and BaFe12O19. However, none have obtained optimum multiferroic properties because they still show inadequate magnetic properties, especially energy values. Therefore, this study aims to enhance the mechanical properties of ceramics synthesized by the sol-gel method. The XRD and permagraph tests with metallographic observations using Scanning Electron Microscopy (SEM) were used to enhance the ceramic compounds by mixing powder based on BaTiO3, BiFeO3, and BaFe12O19. Furthermore, the ratio of the weight composition of the materials varied by 1:1:1; 1:2:2; 2:1:1; 1:2:1 and 2:1:2. The result showed that the best magnetic properties were obtained at the weight composition ratio of 1:2:2 with a magnetic energy value of 48.0897x104 GkA/m. Based on SEM analysis, the sample with this weight ratio was dominated by the BiFeO3 and BaFe12O19 phases with high magnetic properties.
