磁滞现象

In 1956, Meiklejohn and Bean observed that field cooled, partially oxidized, Co particles exhibited hysteresis loops displaced along the magnetic field axis.They attributed this phenomenon to the exchange interaction at the interface between the ferromagnetic Co core and the antiferromagnetic CoO shell.

Meiklejohnc 和 Bean 在 1956 年从成长良好的单晶钴与其表面氧化层的微小颗粒，在强磁场下冷却，观察到磁滞曲线不以磁场零点对称，他们将此现象归因於在内部的 Co核与外部的 CoO 壳之界面产生交互影响。

To enhance the precision of servo systems, friction should be adaptively compensated. With considering the hysteresis in piezo-based micro-feeding components, it is proposed to compensate friction and hysteresis simultaneously in this paper.

But it is strongly nonlinear for vortex, hysteresis and magnetic saturation, so can hardly be identified by traditional identification model.

但是其存在涡流、磁滞和磁饱和等现象，机理复杂而且具有强非线性，用传统的系统辨识模型无法在较大的范围之内精确地逼近实际系统。

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。

Generally speaking, when soft and hard magnetic powder mix with each other, the hysteresis loop of the mixture will be in wasp-waisted shape. The wasp-waisted loop is constricted in the middle section, but is wider above and below section. This phenomenon actually can be found in our experiment, too.

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
