Abstract

The structural and magnetic properties of FeCo–C films produced by electroless plating with different carbohydrates as reducing agents have been investigated. The surface morphology and coercivities of FeCo–C films are dependent on the iron content and type of reducing agent. The local magnetic anisotropy field value increases with a decrease in Fe content. For all systems, deposits with good soft magnetic properties were obtained, with coercivities less than 12 Oe and saturation magnetizations close to 240 emu/g for FeCo–C film with 30% cobalt. The best soft magnetic properties corresponded to the deposits with bcc structure and grain sizes less than 20 nm.

碳水化合物还原FeCo–C薄膜的结构和磁性

摘要

研究了用不同碳水化合物作为还原剂的化学镀法生产的FeCo-C薄膜的结构和磁性。FeCo–C膜的表面形态和矫顽力取决于铁含量和还原剂类型。随着Fe含量的降低，局部磁各向异性场值增加。对于所有系统，均获得了具有良好软磁性能的沉积物，其中含30％钴的FeCo-C薄膜的矫顽力小于12 Oe，饱和磁化强度接近240 emu / g。最佳的软磁性能对应于bcc结构和晶粒尺寸小于20 nm的沉积物。
