of Engineering,Peking University摘 要:Rare-earth-based permanent magnets are one of the most important magnets in both scientific and industrial fields. With the development of technology, nanostructured rare-earth-based permanent magnets with high energy products are highly required. In this article, we will review the progress in chemical synthetic strategies......
nanocomposites and so-called single-phased permanent magnets. Our proposed coercivity mechanism and calculated results agree very well with available experimental data,especially the recently reported high energy products achieved in NdFeB and SmCo based hard/soft multilayers. The hybrid coercivity mechanism can be readily extended to single-phased permanent magnets with defects and other magnetic......

HD Processes in the Production of SmCo5 Permanent Magnets刘涛,李卫,刘兴民,李建奎,郭朝晖摘 要:The application of ‘extreme’ hydrogen-decrepitation (HD) process using high... was about 150 ℃. Cylindrical sintered magnets of composition Sm36Co64 were prepared using HD ball milled, isostatic pressing, vacuum sintering and subsequent heat treatment. The demagnetization curves......
such as Nd2FeI4B and Sm-Co are widely used as high-performance permanent magnets,because they combine high magnetocrystalline anisotropy with reasonable magnetization and Curie temperature.The anisotropy...; crystal-field interaction; interstitial modification; permanent magnets; rare earths; [全文内容正在添加中] ......
