Abstract

BETANCOURT R., J. I.. Nanocrystalline hard magnetic alloys. Rev. mex. fis. [online]. 2002, vol.48, n.4, pp.283-289. ISSN 0035-001X.

The recent progress on the understanding of the physical properties of nanocrystalline hard magnetic alloys, based on Rare earth-Iron-Boron (REFeB) compositions, are reviewed. The discussion includes: fundamental properties, crystal structure, coercivity mechanism, micromagnetic studies and recent applications of these functional alloys. Prospective of future developments are also included.

Keywords : Nanocrystalline magnetic alloys; permanent magnets.
