Abstract: CoFe nanowires were successfully synthesized in nanoporous anodized aluminum oxide (AAO) template by employing DC electrodeposition process. These nanowires have been electrodeposited in the presence of external magnetic field applied parallel (∥) to the axis of nanowires. The effects of externally applied magnetic field on magnetic and structural properties of CoFe nanowires were investigated. X-ray diffraction (XRD) was used to identify crystal structure of the samples. The XRD pattern indicates polycrystalline nature of Cobalt iron nanowires with Body Centered Cubic (BCC) crystal structure. Scanning Electron Microscopy (SEM) images revealed the uniform growth of nanowires inside the template. To explore the magnetic properties of Cobalt iron nanowires, vibrating sample magnetometer (VSM) was employed. It was revealed that for nanowires electrodeposited with external magnetic field, easy axis of magnetization is found parallel (∥) to the nanowire axis with large variation in anisotropic magnetization. Whereas for nanowires electrodeposited without external magnetic, easy axis of magnetization is perpendicular (⊥) to nanowires axis with small variation in anisotropic magnetization.
