摘要: 通过引入外加直流电磁场, 采用KBH4还原法在室温下制备了一维Fe-B非晶态合金纳米线, 并采用X射线衍射(XRD)、电感耦合等离子原子发射光谱仪(ICP-AES)和扫描电子显微镜(SEM)等表征方法研究了产物的结构、组成和形貌. 结果表明, 在直流电磁场的作用下得到了Fe-B非晶态合金纳米线, 所得样品的直径在50-80 nm之间, 长度达到数微米. 通过振动样品磁强计(VSM)研究其磁学性质, 发现外加磁场的引入会显著影响Fe-B非晶态合金的磁学性质. 随着引入磁场强度的增强, 所得样品的饱和磁感应强度和矫顽力明显区别于未引入磁场制备的Fe-B非晶态合金.

Abstract: One dimension (1D) Fe-B amorphous alloy nanowires with diameter of 50-80 nm and length of several micrometers were synthesized under weak DC(direct current) magnetic field by KBH4 reducing in aqueous solution. The structure, composition, and morphology were characterized by X-ray diffraction (XRD), inductively coupled plasma atomic emission spectrometry (ICP-AES), and scanning electron microscope (SEM), respectively. The results revealed that the magnetic field led to the fabrication of Fe-B amorphous alloy nanowire structure. Vibrating sample magnetometer (VSM) has been used to detect the magnetic properties of the samples. The results showed that the inducing of magnetic field had an obvious effect on the magnetic properties of the samples.

Key words: Magnetic field, Fe-B amorphous alloy, Nanowires
