Controllable Synthesis and Magnetic Properties of Ferromagnetic Nanowires and Nanotubes

This article reviews our recent investigations on a general template-based approach for the preparation of one-dimension magnetic nanomaterials. The method involves the synthesis of a desired material within the pores of the ordered anodic aluminum oxide (AAO) membrane. The diameter, orientation, and crystal structure of ferromagnetic nanowires and nanotubes can be controlled using the AAO templates by changing deposition parameters in the process of direct-current electrochemical deposition. The corresponding magnetic properties can be controlled according to the structure and morphology of one-dimension magnetic nanomaterials. This kind of the ordered one-dimension magnetic nanomaterials with unique and tunable physical properties could be used in the fabrication of magnetic nanodevices with high performance and controllability.
