摘要：

YFe1-x Mn (x) O-3 (x = 0.1, 0.2, and 0.4) dense ceramics were prepared by SPS (spark plasma sintering). The dielectric characteristics were evaluated over broad temperature and frequency ranges, and an obvious dielectric relaxation was observed. It was a thermally activated process following the Arrhenius law, and the activated energy decreased with increasing Mn-content. Obvious ferroelectric hysteresis loops were observed at 153 and 123 K for different compositions. The weak ferromagnetic characteristics were detected at room temperature for all compositions, and the remnant magnetization was reduced with increasing Mn-content. These results indicated the multiferroic properties in the Mn-substituted YFeO3 ceramics.
