以自制的孔径为80mn～100nm的AAO为模板,在低温熔融盐体系中采用直流电沉积成功地制备了钆钴合金纳米线阵列。经过SEM观测,钆钴合金纳米线排列有序,尺寸一致;用1 mol.dm-3的NaOH将模板溶掉后并进行TEM检测,钆钴合金纳米线直径为114nm,与孔径直径基本吻合,长度在1.5μm左右,长径比约为15∶1。EDS测定表明纳米线为钆钴合金,其原子百分比为1∶4;XRD分析图谱显示所得到的钆钴合金纳米线为非晶态。对钆钴合金纳米线进行磁性能测定,最大磁能积远远大于铁磁性元素Co,为923.07kJ.m-3,说明钆钴合金具有很好的磁存储能力。
The homemade gadolinium-cobalt-cobalt alloy nanowire arrays were successfully prepared by direct current deposition using AAO with 80nm ~ 100nm pore size as the template. After SEM observation, the gadolinium-cobalt alloy nanowires arranged in order and the same size; with 1 mol.dm-3 of NaOH after the template was dissolved and TEM detection, gadolinium cobalt alloy nanowires diameter of 114nm, and pore diameter basically consistent, Length of about 1.5μm, aspect ratio of about 15: 1. EDS measurement showed that the nanowires were gadolinium-cobalt alloy with an atomic percentage of 1: 4. The XRD analysis showed that the obtained gadolinium-cobalt alloy nanowires were amorphous. The determination of magnetic properties of gadolinium cobalt alloy nanowires, the maximum energy product is far greater than the ferromagnetic element Co, 923.07kJ.m-3, indicating that gadolinium cobalt alloy has good magnetic storage capacity.
