Spin Dependent Hopping in Ti Doped La0.67Ca0.33MnO3 刘宜华1,梅良模1,原晓波1,张汝贞1,王成建1,黄宝歆1 (1.Department of Physics, State Key Laboratory of Crystal Materials, Shandong University, Jinan 250100, China... 0 to 0.17. The most important effect of Ti doping is to introduce spin clusters in the samples due to the distortion of local lattice and the inhomogeneous magnetic structure induced primarily......
Analysis of isothermal forging process and mechanical properties of complex aluminum forging for aviationHU Jian-liang(胡建良), YI You-ping(易幼平), HUANG Shi-quan(黄始全) (School of Mechanical and Electrical Engineering, Central South University, Changsha 410083, China)Abstract:Large complex 7A85 aluminum wing-body joint was forged employing isothermal forging process and its mechanical properties were......
Influence of annealing on spin state of cobalt ions inLa1-xSrxCoO3 (0≤x≤0.5) system JIANG Lizhen1,XU Zhuan2 (1.College of Information and Electronic Engineering, Zhejiang Gongshang University... determined, and their variations with Sr doping and oxygen annealing condition were obtained. The result suggested that by assuming that the Co3+ ions were in the intermediate-spin (IS) state, most......
