Magnetic Properties of Iron-Based Alloy Nanowires upon Heat Treatment

Abstract:

Fe₅₆Co₄₄ alloy nanowires were fabricated by electrodeposition with aluminum oxide template. Transmission Electron Microscope photographs show the nanowires are separate and have no twist with each other. Mossbauer spectroscopy results show the values of the isomer shift, hyperfine splitting and linewidth all decrease with increasing annealing temperature. Vibrating sample magnetometer (VSM) results of the alloy nanowire show that the coercive fields increase with increasing heat treatment temperature when the direction of applied magnetic field perpendicular to the axis of nanowires.
