工艺参数对钴纳米线的结构和磁性能的影响

通过调节沉积电流密度动态地控制钴纳米线择优生长方向,调节沉积液pH值观察其磁各向异性特点,并比较它们的磁性能。利用氧化铝模板直流恒电流电化学沉积方法,调节电流密度和pH值的大小,制备出一系列钴纳米线阵列,并利用XRD衍射仪和VSM振动磁强计测量其磁性能,包括矫顽力、剩磁比和各向异性的特点。通过调节电流制备出了包括101]择优取向、100]择优取向及非晶态等结构的一维钴纳米线阵列,重点分析了具有101]择优取向纳米线阵列的特点;通过调节溶液pH值得出了纳米线磁各向异性的特点,实现了工艺参数对纳米线的结构和性能的控制,总结出了钴纳米线对于101]择优晶向的易磁化规律。

Effect of technical parameters on fabric and magnetism of cobalt nanowires

The experiment dynamicly controled the cobalt nanowires growing preponderantly along the direction easily magnetized via accommodating the density of the constant direct current observed the magnetic anisotropy via accommodating the PH number of the liquid and compared,the magnetic properties.Using the alumina cyclostyle which have well-regulated nanobores to prepare cobalt nanowires,and then measuring the magnetic characteristics with XRD and VSM,including coercive force,remanence and characteristics of an...
