| 1 | Some constructions of projectively flat Finsler metrics显示文摘In this paper, we find some solutions to a system of partial differential equations that characterize the projectively flat Finsler metrics. Further, we discover that some of these metrics actually have the zero flag curvature. | MO Xiaohuan, SHEN Zhongmin & YANG Chunhong LMAM, School of Mathematical Sciences, Peking University, Beijing 100871, China Department of Mathematical Sciences, Indiana University-Purdue University, Indianapolis, IN 46202-3216, USA Department of Mathematics, Inner Mongolia University, Hohhot 010021, China | 2006 | Science China Mathematics2006，49，5： | 15 |
| 2 | Exchange bias for ferromagnetic/antiferromagnetic bilayers with the uniaxial anisotropy being misaligned with the exchange anisotropy显示文摘Using the principle of minimal energy and S-W model,the exchange bias for ferromagnetic/antiferro-magnetic bilayers has been investigated when the uniaxial anisotropy is misaligned with the exchange anisotropy. According to the relation between the energy of the bilayer and the orientation of ferro-magnetic magnetization,it is found that the bilayer will be in the monostable state or bistable state when the external field is absent in the initial magnetization state. The monostable state or bistable state of the bilayer,which determines the angular dependence of exchange bias directly,is controlled by the competition between the exchange anisotropy and uniaxial anisotropy. When the applied field is parallel to the intrinsic easy axes and intrinsic hard axes,one of the switching fields of the hysteresis loop shows an abrupt change,while the other keep continuous by analyzing the magnetization reversal processes. Consequently,the exchange bias field and the coercivity will show a jump phenomenon. The numerical calculations indicate that both the magnitude and direction of the exchange anisotropy will significantly affect the angular dependence of exchange bias. The jump phenomenon of exchange bias is an intrinsic property of the bilayer,which is dependent on the interfacial exchange-coupling constant,the orientation of the exchange anisotropy,the thickness and uniaxial anisotropy constant of the ferromagnetic layer. | BAI YuHao1 & YUN GuoHong1,2 1 College of Physical Science and Technology,Inner Mongolia University,Hohhot 010021,China 2 Key Laboratory of Physics and Chemistry of Functional Materials,College of Physics and Electronic Information,Inner Mongolia Normal University,Hohhot 010022,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 5 |
| 3 | Fluorescence turn-on chemosensor for Hg^(2+) based on a rhodamine derivative and its application in bioimaging显示文摘A fluorescence turn-on chemosensor based on rhodamine B derivative (FD10) has been developed as a highly sensitive chemosensor for Hg2+. A prominent fluorescence enhancement was measured in the presence of Hg2+, which was in agreement with the changes in the absorption spectrum. Furthermore, by means of laser scanning fluorescence microscopy experiments, it was demonstrated that FD10 was cell-permeable and could be used as a fluorescent probe for monitoring Hg2+ in living cells. | LIU Chun1,2, ZHOU ZhiGuo2, GAO Yuan2, YANG Hong2, LI BaoGuo1, LI FuYou2 & HUANG ChunHui2 1 School of Chemistry and Chemical Engineering, Inner Mongolia University, Hohhot 010021, China 2 Department of Chemistry, Fudan University, Shanghai 200433, China | 2009 | Science China Chemistry2009，52，6： | 4 |
