FeSi nanoparticles were synthesized via thermal decomposition of iron pentacarbonyl in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. The TEM images showed that FeSi nanoparticles had cubic shape, but it seemed that the composition was not uniform. According to the EDS results, the Fe:Si ratio of gray-uniform nanopaiticles was almost 1:1, and blacker FeSi nanoparticles contained more Fe atoms. Although FeSi didn't have uniform structure, it still could be proved that the incorporation of Fe and Si existed in a single nanoparticle. All possible structure, lattice, binding, morphology, surface condition would be discussed. These results indicated that perhaps FeSi2 was the main structure of the new products; however, due to incompletely combination and less synthesized time, it might still contain some part of Si and Fe structure. Besides, FeSi nanoparticles preserved the optical properties from Si atoms, but the PL intensity was much lower. The maxima PL peak appeared at 388 nm with the excitation at 300 nm. Their saturation magnetization, remanent magnetization and coercivity were measured by the SQUID, exhibiting their nearly superparamagnetic behavior.

利用热裂解系统可成功将研磨矽奈米粒子及五羰铁结合，制备出铁矽奈米粒子；从穿透式显微镜照片可知其粒子呈现立方体型态，但颜色深浅及组成不均，EDS结果则显示颜色均匀之粒子铁与矽之组成大致为1：1，颜色较深之粒子则含有较高量的铁元素；尽管组成比例并不统一，但单颗粒子同时含有矽与铁两种元素，初步说明铁矽奈米粒子之形成；进行多种结构与表面分析并探讨所有可能之键结、结构及表面元素后，推测铁矽奈米粒子可能以FeSi2之结构形成，并同时包含未重组完成的矽及铁之结构；利用PL分析得知铁矽奈米粒子确实保留矽之放光特性，并在300 nm激发光源下，於波长388 nm处有一最强放光特性峰，但整体发光效益不及研磨矽奈米粒子之结果；最后，利用超导量子干涉磁化仪量测其饱和磁化量、残留磁化量、与矫顽磁力，发现磁滞现象并不明显而几乎呈超顺磁性。

Further analysis of the exchange energies, magnetocrystalline anisotropy energies, Zeeman energies and demagnetizing energies show that the demagnetizing field is the main factor to decide the coercivity in medium.

When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires. The coercivity of the Fe nanowire arrays in the diameter of 16nm is 2000Oe at 300K, and it will increase to 2800Oe when the temperature decreases to 5K.

不同直径的Fe纳米线的磁滞回线均表明沿着线的方向均表现出shearing effect，表明其中存在一个等效退磁场，它来源于线间的偶极相互作用。16m的Fe纳米线的矫顽力室温下为2000Oe，5K时则达到2800Oe。

Similar to Pt/Co multilayers, the PMA in the Co-Pt alloy film originates from the reduction of symmetry in the interface between magnetic and non-magnetic layers. Addition of a small amount of Ni in the Co-Pt alloy film leads to an obvious decrease in the Curie temperature, but the decreases in Kerr rotaion and PMA are quite limited. Furthermore, it promotes the growth of grains and roughens the film surface and thus enhances the coercivity of the film, which are of advantage for short-wavelength MO recording.

在Co-Pt合金薄膜中加入少量的Ni可促进晶粒生长、增加表面粗糙度、提高矫顽力，并且在不明显减弱垂直磁各向异性和极克尔角的情况下，能有效地降低居里温度，有利于短波长高密度磁光存储。

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.

我们并发现溅镀Fe之温度与瓦数，并不会对结构或是磁性质有显著的影响，Fe厚度的改变虽然也不会改变结构，但是对Cr/Pt/FePt/Fe磁性质却有明显的变化，当Fe厚度薄时(3、5 nm)，在Fe和FePt界面仅有弱的交换耦合力产生，Fe厚度是10 nm时，此时交换耦合力为最强，厚度再增加到15、20 nm时，Hc反而略为上升，同样的我们量测DCD曲线，也证实了Fe厚度10 nm的确有交换耦合力存在。
