采用直流溅射和热处理技术制备了两个各向同性的纳米结构Fe Pt永磁合金薄膜系列 ,并研究了它们的结构和磁性 .研究表明 ,在富Fe双相纳米结构Fe Pt永磁合金薄膜中 ,仅由硬磁的FePt相与软磁的Fe3Pt相组成 ;在同一系列中 ,随Fe层厚度的增加 ,饱和磁极化强度和剩磁明显增大 .由Kelly Henkel图研究指出 ,在上述Fe Pt纳米结构永磁合金薄膜中 ,磁相互作用主要由近邻纳米晶粒间的铁磁交换相互作用控制 Two isotropic nanostructured Fe Pt permanent magnet alloy films were prepared by direct current sputtering and heat treatment, and their structures and magnetic properties were also studied. The results show that in the Fe-rich dual-phase nanostructured Fe Pt permanent magnetic alloy films , Only by the hard magnetic FePt phase and the soft magnetic Fe3Pt phase; in the same series, with the increase of Fe layer thickness, saturation magnetic polarization and remanence significantly increased by the Kelly Henkel graph study pointed out that in the Fe In Pt nanostructured permanent magnet alloy films, the magnetic interaction is mainly controlled by the ferromagnetic exchange interaction between the neighboring nanocrystals
