论文摘要
通过将NAHB4作为还原剂进行还原反应方法制备了Alpha Fe2O3粉末，并遵循了常规的烧结过程。带有Rietveld精炼曲线的XRD模式表明，制备的Fe2O3具有刚毛结构（赤铁矿）。 VSM回路表现出明显的室温弱铁磁症，形状各向异性效应可能引入了捏合的磁滞回路。 α-FE2O3与“五倍”铁电磁滞回路的同时铁电行为批准，该结构化的FE2O3可以称为一种新型的多效材料。
Alpha Fe2O3 powders have been prepared by the reduction reaction method with NaHB4 as reducing agent and followed a conventional sintering process. The XRD pattern with Rietveld refinement profile reveal that the prepared Fe2O3 with corundum structure (hematite). VSM loop exhibits obvious room-temperature weak ferromagnetism, a pinched hysteresis loop may introduced by the shape anisotropy effect. The simultaneous ferroelectric behavior of α-Fe2O3 with "five-fold" ferroelectric hysteresis loops approves that this structured Fe2O3 can be known as a novel multiferroic material.
