Abstract:
Sm-Fe-B GMFs were prepared on glass substrate by ion beam sputtering deposition method (IBSD). Different stresses were applied during an annealing treatment and the effects of free and stress annealing to magnetic domain structure. The soft magnetic properties and magnetostriction for Sm-Fe-B GMFs were studied. The result showed that the magnetic domain structure of Sm-Fe-B GMFs changed significantly by free annealing and stress annealing, and the soft magnetic properties and magnetostrictive properties in low field were greatly improved for the change of microstructure and stress state; Compared with free-annealing-state samples, stress-annealing-state sample had the obviously vertical anisotropy, and the saturated magnetostriction was improved greatly, although the magnetic sensitivity decreased slightly in low field. ©, 2014, Chinese Rare Earth Society.
