A new Chinese regulatory policy on the supply of rare earth magnets, which came into effect on April 4, requires exporters to ...

Abstract: A systematic study has been undertaken to understand the evolution of microstructure, microchemistry, and coercivity of sintered Sm(Co/sub bal/Cu/sub 0.06/Fe/sub 0.015/Zr/sub 0.027/)/sub 6.4 ...

Abstract: The coercivity mechanism of (Co/Pt) multilayers with high H/sub c/ and high squareness fabricated by sputtering is mainly due to the wall pinning rather than the nucleation process. In order ...
