The application of expansion constraint during the grain-boundary diffusion process using Nd70Cu30 eutectic alloy minimizes the remanence loss for the coercivity enhancement by optimizing the volume fraction of the Nd(Cu)-rich non-ferromagnetic inter

In order to understand the origin of the coercivity reduction in a sintered Nd–Fe–B magnet that is annealed below an optimal annealing temperature, we performed focused ion beam/scanning electron microscopy tomography of post-sinter annealed magn

Nd2Fe14B thin films were fabricated with a DC magnetron sputtering system. X-ray diffraction experiments and the Rietveld analysis showd that the crystallites of the Nd2Fe14B phase were highly oriented perpendicular to the film plane. In addition to

One approach to solve the so-called coercivity problem on Nd-Fe-B permanent magnet is to investigate the magnetization reversal process. The magnetization reversal is a transition event between two energy local minima separated by an energy barrier.
