| 摘 要： | 用直流磁控溅射的方法在室温Si基片上制备体积百分比分别为5%,10%,20%,40%的系列Ni Cu磁性复合团簇镶嵌薄膜样品,并利用X射线衍射技术、振动样品磁强计等方法对团簇的微结构和磁性能进行了测试研究。微结构分析表明:薄膜呈多晶状态,晶体结构仍为面心立方,随着Ni组份的增加,复合团簇膜的晶粒尺寸与平均晶格常数均减小。磁性分析表明:所有样品均表现出铁磁性,随着Ni百分比含量的增加,矫顽力Hc减小,饱和磁化强度MS增加,磁性逐渐增强,且尺寸效应明显。

| Abstract: | Ni-Cu composite films embedded with Ni nanoparticles of different volume fraction were prepared by DC magnetron sputtering, and analyzed by X-ray diffraction and vibration sample magnetoscope. XRD results suggested that with Ni composition increasing , the lattice constant of Ni nanoparticles decreased. The magnetic measurement results show that the magnetic properties were varied with composition and grain size of the films. With increasing Ni fraction , coercive force Hc reduces and saturation magnetization Ms enhances. |
