中文摘要：

成功地合成出了高性能2:14:1和2:17结构硬磁相/Fe软磁相铁基纳米稀土复合永磁材料以及1:6:6:结构铽锰基和各向异性的钐钴基纳米晶稀土永磁材料,对纳米尺度下永磁经材料的矫顽力机制给出了合理的解释.在镓替代的2:17结构稀土铁化合物中,观察到由于镓原子的择优占位,引起了居里温度随镓含量的增加而升高的反常现象,导致了化合物的各向异性在室温由易面转变为易轴.发现NaZn13型结构的稀土-铁基化合物在室温具有大的磁熵变,其磁熵变值是金属钆的2倍以上.首次发现自旋玻璃锰氧化合La0.67Ca0.33(Mn.Fe)O3在低温下具有分步磁化行为和与之相关的超大磁电阻效应,并证明了分步磁化行为来源于自旋玻璃态中反铁磁团簇在外声下的熔化.
