This project proposed here aims to research the synthesis and growth-control mechanism of L10 type alloys inside multiwall carbon nanotubes deeply by the newly designed chemical vapour deposition system. Based on a lot of experients, we will explore the impact of various cooling methods and different mass ratios of precursor materials and the reaction temperature and other parameters on the growth of alloy nanowire, and clarify the optimal growth conditions of L10 type alloy nanowires, so that we can lay the foundation of large-scale production of multiwall carbon nanotubes filled with L10 type alloy nanowires. Combinig the theoretical and experimental research, this work will allow us to understand the exceptional magnetic and electronic properties of L10 type alloy nanowires. Besides, this work will further clarity the relationship between the exceptional magnetic and electronic properties and the application of the eletronic devices based on magnetism and spin. Furthermore, if we can find the suitanle polymers, we will be able to create novel flexible prototypes for revolutinary applications. Finally, this work will provide a strong theoretical and technical support for the industrialization of new generation of magnetic and spin-based novel devices.
