FePt纳米薄膜研究进展

由于FePt在超高密度磁存储材料方面的广阔应用前景及其局限性,研究人员对FePT薄膜进行了大量的研究及改性.根据国外近期在此领域的研究现状,综述了单相、复相及掺杂FePt薄膜的制备以及对结构和性质的影响.复相或掺杂主要是通过结构的改变来降低L10晶相转变温度和FePt颗粒的大小,通过其耦合作用来影响FePt薄膜的磁学性能,使其成为超高密度存储器材料.

Progress of Study on Nano-FePt Film

The requirements for ultra-high density magnetic recording have driven the development of new magnetic thin film media with smaller grains,higher coercivity,and minimal exchange coupling between neighboring grains.Nano-FePt film has been viewed as a promising candidate for future recording media applications.Since it has some restriction in practice, many studies concentrate on nano-FePt films.This paper,based on the recent researches in this field.discusses the preparation, structure and character of nano-FePt films.They effectively reduce the formation temperature of L1_0-FePt ordering and impedes the growth of FePt grains through the way of change the strucure of FePt films.And the magnetic character of nano-FePt films can be improved to be the supeior material of future magnetic recording material.
