Temperature stability of magnetic field for periodic permanent-magnet focusing system被引量：1
《Rare Metals》2014年第2期180-184,共5页Li Li Jian-Ya Chen Yun-Jie Liu 
financially supported by the National Natural Science Foundation of China (No. 61001120)
In this study, finite element analysis based on an Ansoft Maxwell software was used to reveal the temperature stability of a magnet ring and the equivalent structural periodic permanent-magnet（PPM） focusing system. ...

Effect of Sm Volatilization on Magnetic Microstructures of Sintered Sm（Co,Fe,Cu,Zr）z Magnets at High Temperatures
《Chinese Physics Letters》2006年第5期1289-1292,共4页夏爱林 方以坤 郭朝晖 李卫 韩宝善 
Supported by the National Natural Science Foundation of China under Grant Nos 10374110 and 50201004.
We present a magnetic force microscopy study of surface magnetic microstructure changes at high temperatures in 2：17-type Sm（Co,Fe, Cu,Zr）z （z ～ 7.4） magnets. Surface magnetic microstructures are found to change...

Exchange Coupling and Stability of SmCo7-xHfx
《Chinese Physics Letters》2005年第11期2910-2913,共4页张昌文 李华 董建敏 王永娟 潘风春 郭永权 李卫 
Supported by the National High-Technology Research and Development Programme of China under Grant No 2002AA324050, and the Natural Science Foundation of Shandong Province under Grant Nos Y2002D9 and Y2004A10.
Electronic structure of SmCo7-xHfx compound is calculated by using the multi-scattering Xα method. It is shown that a few of electrons can transfer to the Sm 5d orbital due to orbital hybridization between Sm and Co ...
