THE ENHANCED FERROMAGNETIC PROPERTY OF BIFEO3-YMNO3 SYSTEM
Single-phase multiferroic materials are important both in basic research and practical applications. In this research, solid solutions of (1-χ) BiFeO3-;χYMnO3 (x = 0, 0.05, 0.1) were synthesized by rapid liquid phase sintering method. The phase structures, leakage current density, magnetic and ferroelectric properties were investigated. All the solid solution samples show a perovskite phase structure. The addition of YMnO3 content was found to enhance the magnetization of the solid solutions, but the leakage current density was degenerated. Saturated electric hysteresis loop was obtained in the sample with 5% of YMnO3 fraction at room temperature, while at 10% of YMnO3 content the polarization loop present a leakage characteristic. The investigated materials may be promising as the diluted magnetic semiconductors in related applications.
