Synthesis and Characterization of Ba0.8Sr0.2TiO3-Co0.8Zn0.2Fe2O4 Multiferroic Composites Prepared by Solid State Reaction Method

摘要

The magnetic material is now very much used in the various purposes. They are also used in the electrical application. In this paper we have studied the various characteristics like magnetic, structural and other physical properties of barium strontium titanate-cobalt zinc ferrite prepared by the solid state method. The crystal structure or phase is studied by XRD. Zinc and strontium ion is substituted about 20 percent in place of cobalt and barium respectively. The composites prepared in 60:40, 70:30, 80:20 percent respectively. The sintering behavior is studied at different temperature. Microstructure also analysis using FESEM. Thermal expansion is studied using dilatometer. During preparation of Ba0.8Sr0.2- TiO3 and Co0.8 Zn 0.2Fe2O4 by solid route method they were calcined at 900o C for two hours and 950o C for one hour respectively. Then the sample are mixed by isopropyl alcohol and dried. Pellet were made and fired at 11750 c and characterization were studied
