Fabrication of ferromagnetic coaxial nanowires and their magneto-optical effects

Abstract

随着光信息技术和纳米制备技术的发展,磁光效应及各种磁光器件因其独特的性能和广阔的应用前景吸引了人们广泛的关注。由于块体材料和单纯薄膜材料的磁光响应不高,限制了磁光器件的发展。因此,如何通过新兴技术实现法拉第效应的增强已成为研究热点。近年来,许多研究表明通过结构优化,如采用纳米线、纳米圆盘等新型纳米结构,可增强材料的法拉第效应;同时,研究发现通过贵金属纳米颗粒诱导的表面等离激元共振也可以增强该效应。本文将结合上述两种增强法拉第效应的方法,制备贵金属Ag纳米粒子修饰的铁磁同轴纳米线,进一步提升材料的磁光性能,具体研究内容和成果如下: 1.铁磁同轴纳米线制备 我们结合化学气相沉积、磁控溅射和快速...With the rapid development of optical information technology and nanotechnology, the magneto-optical (MO) effect has attracted considerable research attention because of its special performance and wide range of potential applications. However, the MO Faraday effect in common ferromagnetic (FM) films or bulks are insufficient for device applications. Hence, how to enhance MO effect is a hot proble...学位:工学硕士院系专业:物理科学与技术学院_工程硕士(电子与通信工程)学号:1982013115299
