Controllable one dimensional FePt nanomaterials synthesized by chemical method

Recently, intensive attentions have been paid on low dimensional FePt nanomaterials because of their chemical stability and potential applications in high-density data storage and high-performance permanent magnets. These applications strongly relate to morphology and size of the FePt nanomaterials. The FePt nanomaterials with varied shapes, including sphere-like nanoparticles, cube-like nanoparticles, nanorods, and nanowires, have been successfully synthesized by using different methods. In these materials, one dimensional (1D) FePt nanomaterials have been becoming a fascinating field, since the nanomaterials have obvious shape anisotropy that results into unique magnetic performances. However, controllable synthesis for 1D FePt nanomaterials still is an insurmountable problem. An improved understanding of growth mechanism is significant for controllable synthesis of 1D FePt nanomaterials. In this work, controlled FePt nanowires have been synthesized. The growth process of the nanowires has been investigated. It´s expected to understand the growth mechanism of 1D FePt nanomaterials.
