摘要
L1_(0)相FePt和CoPt薄膜因具有较高的各向异性、高的饱和磁化强度以及良好的抗氧化化学稳定性,已经成为高密度磁存储介质材料最佳候选者。隔离介质在L1_(0)相Fe(Co)Pt薄膜中应用,可以起到细化晶粒、提高存储密度、促进柱状粒子生长、增强磁晶各向异性、降低晶粒之间磁偶极相互作用及提高信噪比等作用。概括了非金属、金属和氧化物三类不同隔离介质对Fe(Co)Pt薄膜的结构和磁性能的影响概况和研究进展,总结了各种隔离介质作用的优缺点,展望了隔离介质研究和多层设计在未来的发展趋势。
Due to its high anisotropy,high saturation magnetization and excellent chemical stability against oxidation,L1_(0) Fe(Co)Pt film has become the best candidate for high-density magnetic storage media materials.The application of segregant in the L1_(0) Fe(Co)Pt film can refine particles,increase the storage density,promote the growth of columnar particles,increase the magnetocrystalline anisotropy,reduce the magnetic dipole interaction and improve the signal-to-noise ratio.This paper has reviewed the general situation and research progress of the effects of different segregants on structural and magnetic properties of Fe(Co)Pt films.The advantages and disadvantages of the segregants have been summarized.In addition,the future development trend of the segregant research and the multilayer design has been explained.
