Epitaxial growth of magnetic nanowires by chemical vapor transport

This chapter provides some background on the epitaxial growth of various nanowires (NWs) with interesting magnetic properties that have been developed using a simple and robust chemical vapor transport (CVT) technique. To epitaxially grow single-crystalline magnetic NWs, a suitable single-crystalline substrate should be used, and the reaction conditions need to be specifically optimized. This chapter discusses the diffusion-driven crystal structure transformation method after a CVT reaction, as well as a direct one-step CVT reaction, as synthetic approaches to obtaining epitaxial arrays of transition metal and transition metal-containing compound NWs. Such epitaxially grown magnetic NWs can be used as advanced building blocks for a wide range of spintronic applications.
