Structure, Magnetic and Electronic Transport Properties of New-Type Magnetic Nanocluster Assembled Thin Films

Abstract

纳米粒子以及由它们构成的纳米结构材料由于具有尺寸效应、量子限域效应和界面效应,通常显示出许多不同于常规块体材料的磁、光、电等特性,在现代工业、国防和高新技术发展中充当着重要的角色。纳米粒子复合薄膜材料由于其兼有复合材料和纳米材料两者的优点,引起了越来越多的关注,并成为一个重要的前沿研究领域。 本论文的研究工作包括两个方面:1)利用纳米粒子束流复合薄膜沉积系统将由等离子体溅射惰性气体冷凝法制备的Fe65Co35合金纳米粒子原位封装到由常规磁控溅射制备的Ni0.5Zn0.5Fe2O4薄膜中,制备了[email protected]双磁性相纳米复合薄膜,并系统地研究了合金纳米粒子含量...Compared with the bulk materials, nanoparticles and nanostructure materials show many different magnetic, optical and electrical properties due to their size effect, quantum confinement and interfacial effect, and play an important role in the development of modern industry, national defence and high technology field. Especially the nanocomposite materials have drawn extensive attentions and becom...学位:工学博士院系专业:材料学院_材料物理与化学学号:2072012015331
