NdFeB bulk magnets were synthesized by spark plasma sintering (SPS) using the precursors of melt spun nanocrystalline Nd10.15Pr1.86Fe80.41Al1.67B5.91 ribbons mixed with Zn and/or Dy2O3 powders. The addition of 0.6 wt.% Zn or 2 wt.% Dy2O3 is effective in improving the magnetic properties of the magnets, and their coercivities are about 11% or 15%, respectively, higher than that of the additive free...
Soft magnetic films (SMFs) are key materials for miniaturization and multifunctionality of radio frequency and microwave components and integrated circuits (ICs) due to the good high-frequency soft magnetic performances and the compatibility to IC processing technologies. Magnetic micro-inductors are one of widely used microwave IC components. The SMFs in magnetic micro-inductors should have a well-defined...
The main problems with the sintered NdFeB magnets are their bad formability, low oxidation resistance, and poor temperature stability. Relatively large grain size, typically more than 3 mm, is also not beneficial to the high coercivity. Current efforts are directed to improve the magnetic properties and reduce the cost of NdFeB magnets by compositional modification, microstructure optimization, and...
Rare earth-cobalt based magnetic materials have attracted considerable attention due to their large anisotropy eld (HA), high saturation magnetizations (Ms), and high Curie temperatures (TC). As the first generation of rare earth-transition metal (RE-TM) based permanent magnet, SmCo5 possesses extraordinary high anisotropy led over 240 kOe, and nanocrystalline SmCo5 magnet bears coercivity as high...
