在从1967-1992年连续25年研制固态磁存储器的故事中,中国没有缺席。1970年代初,中国科学院物理研究所磁学室磁泡组11个人从生长基片单晶,制备单晶磁泡薄膜和进行磁泡测量三方面开始磁泡材料的研制。当时文章作者负责测量,设计制作了磁泡测量装置。为了表征磁泡薄膜,发现了含有“一盘”软磁畴段的H图形,并找到了“脉冲偏磁场作用下硬磁泡的形成”的研究课题。这使作者在1980年代初经受住了磁泡下马的冲击,迎来了1983年布洛赫线存储器方案的提出,发觉已具有研究其机理的条件,最终成为该存储器的终结者,并在1991年国际J.Mag.Mag.Mater.杂志第100纪念卷中荣幸地为“China”占了一席之地。从1992年以来,时间又过去了25年,但活生生的磁泡总在,当年报废的磁泡测量装置已经更新。盼望大学生和刚入门的研究者喜欢这台能显示赏心悦目的磁泡畴运动,能生动阐述铁磁学物理基础的研究导向性的物理实验设备。
China has not been absent from the story of developing solid-state magnetic memory for 25 consecutive years from 1967 to 1992. In the early 1970s, 11 individuals in the magnetophoresis chamber of the Institute of Physics, Chinese Academy of Sciences began to develop the bubble material from three aspects: growing a single crystal of a substrate, preparing a single crystal bubble film and measuring a bubble. Article author was responsible for the measurement, design and manufacture of bubble measuring device. In order to characterize the bubble film, an H-pattern with “soft” domains was found, and a “research on the formation of hard bubble under pulsed magnetic field” was found. This led the author to endure the impact of the dislocation of the bubble in the early 1980s and ushered in the proposal of the Bloch line memory scheme in 1983 and found that it had the condition to study its mechanism and eventually become the terminator of this memory and in 1991 Year International J. Magn. Mag. Mater. 100 Memorial Volume honored to “China ” a place. Since 1992, time has passed 25 years, but the living bubble is always there, and the scrapped bubble measuring device has been updated. Hopefully, college students and beginners can enjoy the research-oriented physical experiment equipment that can demonstrate the delightful magnetic bubble domain movement and vividly expound on the physics of ferromagnetics.
