多铁性BiFeO3-BiMnO3纸板磁结构效应的第一性原理研究
Magnetostructural Effect in the Multiferroic BiFeO3-BiMnO3 Checkerboard from First Principles
摘要:
使用第一性原理计算,我们提出了一个磁结构效应的BiFeO 3-BiMnO 3纳米棋盘,没有发现在散装母体化合物或BiFeO 3-BiMnO 3超晶格。我们还表明,原子尺度的棋盘格具有多铁性基态与每个constitent材料所需的属性:极性和亚铁磁分别由于BiFeO 3和BiMnO 3。
英文摘要:
Using first principles calculations, we present a magnetostructural effect in the BiFeO3-BiMnO3 nanocheckerboard that is not found in either bulk parent compound or in BiFeO3-BiMnO3 superlattices. We also demonstrate that the atomic-scale checkerboard has a multiferroic ground state with the desired properties of each constitutent material: polar and ferrimagnetic due to BiFeO3 and BiMnO3 respectively.
