چکیده
This study presents the structural and magnetic properties of melt-spun , , and alloys. Appreciable permanent-magnet properties with a magnetocrystalline anisotropy of about 9.6–16.5 , a magnetic polarization –10.6 kG, and coercivities –3.0 kOe were obtained by varying the composition of these alloys. Structural analysis reveals that the positions of x-ray diffraction peaks of show good agreement with those corresponding to an orthorhombic structure having lattice parameters of about , , and. Based on these results, a model crystal structure for is developed and used to estimate the magnetic properties of using density-functional calculations, which agree with the experimental results.

متن کاملRare-earth Permanent Magnets: New Magnet Materials and Applications
The introduction of rare-earth permanent magnets based on samarium-cobalt in about 1970, and neodymium-iron-boron magnets in the mid-nineteen eighties, has ushered in a new era in hard magnetic materials. This has resulted in a dramatic improvement in permanent magnet performance, with neodymium-iron-boron (Nd2Fe14B) magnets having a magnetic energy product up to an order of magnitude greater t...
