摘要

研究了碳铂缓冲层（BL）作为抑制团聚的金属岛BL沉积的颗粒膜的纳米结构和磁性能。与沉积在凝聚BL上的颗粒膜相比，碳BL促进了颗粒的分离。厚度大于0.6 nm、Pt含量为40 ~ 70 vol%的BL对晶粒团聚有较好的抑制作用。与Carbon BL相似，用Carbon- pt BL制备的颗粒膜中的（001）面内组分也显著减少。抑制物质向颗粒膜的扩散会提高颗粒膜的磁各向异性能。

Effect of an agglomeration-suppressed metal island buffer layer on nanostructure of FePt-oxide granular films for heat assisted magnetic recording media

Investigation of nanostructure and magnetic properties of granular films deposited with a Carbon-Pt buffer layer (BL) as an agglomeration-suppressed metal island BL is reported. Compared with the granular film deposited on an agglomerated BL, Carbon BL, grains separation are promoted. BL with thickness thicker than 0.6 nm and Pt content of 40–70 vol% in the BL is effective to suppress the grain agglomeration. Similar to Carbon BL, (001) in-plane component in the granular film fabricated with Carbon-Pt BL is also reduced significantly. The suppression of material diffusion from BL to the granular films will enhance magnetic anisotropy energy of the granular films.

期刊介绍： In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
