我们报道了Camn(7)O(12)是一种新的磁性多铁材料。铁电极化的出现与磁相变(类似于90K)相一致，这表明存在由磁性引起的铁电性，这一点得到了其强烈的磁电响应的进一步证实。与其他已知的磁性多铁体相比，Camn(7)O(12)表现出诱人的多铁性，如高的铁电临界温度和大的极化。更重要的是，这些结果为在掺杂氧化物目录中寻找磁性多铁化合物开辟了一条新的途径。
We report that CaMn(7)O(12) is a new magnetic multiferroic material. The appearance of a ferroelectric polarization coinciding with the magnetic phase transition (similar to 90 K) suggests the presence of ferroelectricity induced by magnetism, further confirmed by its strong magnetoelectric response. With respect to other known magnetic multiferroics, CaMn(7)O(12) displays attractive multiferroic properties, such as a high ferroelectric critical temperature and large polarization. More importantly, these results open a new avenue to search for magnetic multiferroics in the catalog of doped oxides.
