The spin glass behavior predicted before by Monte Carlo calculation is observed in the MnTe film. This behavior is destroyed by adding Cr in the MnTe film. The temperature dependence of magnetization shows a sharp rise at around 66 K  due to the magneto-elastic coupling. Metallic behavior is observed in the MnTe film in the temperature range 120-220 K  which is ascribed to the magnetic ordering. The metallic behavior disappears with adding Cr  because adding Cr ions destroys the magnetic ordering which is mediated by the sp-d exchange interaction between the Cr ions. 2012 Elsevier B.V.   全氟辛酸和全氟辛烷磺酸盐的毒理效应研究 学位论文  OAI收割 博士, 北京: 中国科学院研究生院, 2009 崔琳 收藏  |  浏览/下载：100/0  |  提交时间：2010/05/27 全氟辛酸  全氟辛烷磺酸盐  毒理学效应  富集排泄  共价耦合 perfluorooctanoic acid (PFOA)  perfluorooctane sulfonate (PFOS)  toxicological effects  accumulation and excretion  covalently coupling.   High power diode laser with beam coupling (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Wang L.;  Liu Y.;  Wang L.;  Liu Y.;  Liu Y. 收藏  |  浏览/下载：59/0  |  提交时间：2013/03/25 As the increasing applications of the semiconductor lasers in the laser processing  the single 2-D stack optic-power density has not satisfied the actual requirements. It demands to couple several diode laser stack beams to one to improve the brightness  and it becomes the central issue to adopt the appropriate beam coupling technology which would offer high quality and high efficiency. In this paper  it mainly introduces the beam shaping and the technology of spatial coupling  polarization coupling  and wavelength coupling. The coupling key elements are presented and indicated. Finally  the development of the diode laser on beam coupling in our country fell behind through analyzing the statement of the world. Our lab is studying on polarization coupling and wavelength coupling. We gain some results by phase  which the polarization coupling efficiency can achieve 90% for two LD stacks with seven bars whose luminous wavelength is 975nm and980nm.By two 808nm diode laser coupling  the efficiency of 60% can be achieved after focusing to the beam size of 22mm2. 2008 SPIE.
