Improving Magnetic Properties of BiFeO₃-BaFe₁₂O₁₉ Solid Solution by Different Sintering Time and Temperatures of Sol-Gel Method

Abstract

<jats:p>Synthesis of BiFeO3-BaFe12O19 solid solution is aimed to enhanced magnetic properties of the material which can improve the quality of multiferroic properties of material. As we know that BiFeO3 is a multiferroic material if it is in single phase but unfortunately it is difficult to produce BiFeO3 in single phase, which can cause a large current leakage arising from non stoichiometric. It used sol gel method to produce BiFeO3-BaFe12O19 solid solution with weight ratio of 1;1. To know magnetic properties, it was used permagraph test which is type of MPS magnet – Physic EP3 – Permagraph L . The sintering temperature was 750, 800 and 850oC for 8, 10 and 12 hours respectively. There is no regularity in increasing and decreasing of remanent and coersivity properties with increasing sinter temperatures and time of sintering but there is an increasing magnetic energy with increasing sinter temperatures and time of sintering. The highest value of magnetic energy, 10.716 GkA/m belongs to powder sintered at 850oC for 12 hours.</jats:p>

“…The multiferroic material that has been successfully synthesized and shows better value of the MagnetoElectric (ME) coupling constant is based on ferrite material [1]. The material shows a large voltage value of 130 volts when given the effect of external magnetic field only 150 Gauss.…”
