High coercivity in rapidly quenched Sm(Fe, T)12-type magnets
- 1. Department of Physics, Kansas State University, Manhattan, Kansas 66506
Description
The magnetic and structural properties of melt-spun Sm(FeT)12 alloys where T = Ti,V,Al,Cu,Ga,Si and with some containing small amounts of B and C have been studied. The samples are magnetically soft in the as-quenched state. High coercive fields are developed upon heating the samples at temperatures ranging from 750 to 1050 0C. The tetragonal ThMn12-type structure was found in all the alloys after annealing. The highest coercivities have been obtained on a Sm/sub 10/Fe/sub 80/Ti/sub 7.5/B/sub 2.5/ sample with H/sub c/ ≅7.7 kOe. These coercivities are much higher than those obtained previously and make these alloys good candidates for permanent magnet development
