【摘要】

：

稀土正铁氧体HoFeO3具有Fe3+ 和Ho3+ 两套磁性子晶格,因此展现出丰富的磁性质.已有的研究表明:在T＜647 K以下,Fe3+发生反铁磁有序,反铁磁轴沿a方向,c方向具有弱的铁磁分量;51 K＜T＜62 K,Fe3+发生自旋变向,反铁磁轴由a方向逐渐变到c方向;T＜51 K,反铁磁轴沿c方向;当T＜4.5 K时,Ho3+发生反铁磁有序.

全致密各向异性SmCo5纳米晶磁体的结构与磁性能研究

采用熔体快淬或高能球磨的方法制备的SmCo5纳米晶永磁材料具有高矫顽力和高居里温度[1],具有潜在的应用价值.但这类材料是磁各向同性的,磁能积较低,在很大程度上限制了实际应用.对此,我们采用放电等离子热变形技术研制了各向异性SmCo5纳米晶磁体[2],本文对这种新型磁体的结构和磁性能进行了表征.
