Title: Synthesis and Characterization of FeCo Nanowires with High Coercivity

Abstract

Ferromagnetic FeCo nanocrystals with high coercivity have been synthesized using a reductive decomposition method. The sizes and shapes of the nanocrystals were found to be dependent on reaction parameters such as the surfactant ratio, the precursor concentration and the heating rate. Synthesized nanocrystals have a body-centered cubic crystal structure for both particles and nanowires and the (110) crystalline direction is along the long axis of the nanowires. The coercivity and magnetization of the FeCo nanocrystals are found to be dependent on morphology. Nanowires of Fe 60Co 40 with saturation magnetization of 92 emu g -1 and coercive force of 1.2 kOe have been obtained in this study.
