一、前言关于磁带用的以铁为主体的微粒子磁粉的研究,特别是关于小于1μm的微粒子的系统研究更是相当深澳。以人类最熟悉的铁为对象,用磁性方法,能很容易地推断出微粒子的结构因记录技术的发展和磁带的普及,要求有性能更好的磁性材料可以说这一背景促进了研究。目前对常用的γ-Fe_2O_3粒子。以 I. INTRODUCTION The research on iron-based fine particle magnetic powders for magnetic tapes, especially the systematic study on fine particles smaller than 1μm, is quite deep. Using the magnetic method, it is easy to deduce the structure of the microparticle by the magnetic method, which is most familiar to human beings. The background of the microparticle structure is demanded because of the development of the recording technology and the popularity of the magnetic tape. Currently on the common γ-Fe_2O_3 particles.
