Synthesis and Magnetic Property of Fe-B Amorphous Alloy Nanowires by Inducing DC Magnetic Field

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 obvious effect on the magnetic properties of the samples.
