一种ICF用新型可阵列反射镜架结构

运用并联机构原理设计了一种新型惯性约束聚变（Inetial Confinement Fusion, ICF）用可阵列反射镜架结构,并用坐标变换方法分析了机构的调整正交性与旋转轴正交性之间的关系.装置的实际测试结果表明调整正交性与分析结果一致,并且反射镜架的稳定性以及调节准确度均能符合ICF装置的使用要求.

Analysis on a new type magneto-optical disk for blue lasers

The conventional TbFeCo magneto-optical (MO) medium has a relatively smaller Kerr rotation angle in the blue region than in the red. With the recording wavelength gradually moving to the short wavelength, if TbFeCo is still used as recording medium, the conventional MO disk structure must be optimized to get a larger carrier to noise ratio (CNR). Sabi et al. have found that adding a metal layer attached to the TbFeCo film as thermal control layer is a useful way to get a high CNR. In this paper, we proved this through calculation, and carried out optimization of the new type of disk. Calculation results showed that the new structure is useful in preventing an excessive temperature increase, and has a better thermal response. (c) 2005 Elsevier B.V. All rights reserved.

GdFeCo／TbFeCo磁超分辨磁光记录薄膜研究

用磁控溅射法制备了GdFeCo／TbFeCo交换耦合两层薄膜，利用不同温度的克尔磁滞回线和VSM磁滞回线研究了读出层（GdFeCo）变温磁化方向变化过程．结果表明，随温度升高读出层从平面磁化转变为垂直磁化，交换耦合两层薄膜具有中心孔探测磁超分辨的基本性能．转变过程主要受饱和磁化强度（Ms）的影响，在GdFeCo的补偿温度附近，读出层的磁化强度较小，退磁场能也较小，在交换耦合的作用下，使读出层（GdFeCo）的磁化方向发生转变．磁化方向的转变在75℃～125℃的温度范围内变化较快．
