| 中文摘要 | Nanocrystalline exchange coupled Sm2Fe14.5 divided by nCu0.5Ga2C2 magnets with enhanced remanence were produced using melt spinning. Starting from nearly single phase Sm2Fe14.5Cu0.5Ga2C2 alloys, the content of additional alpha-Fe in the composite magnets was stepwise increased up to more than 50 wt.%. A maximum remanence ratio of M-r/M-s=0.65 was found in samples containing 8.3 wt.% alpha-Fe, whereas the coercive field was mu(0)H(c)=1.6 T for this composition. Magnetic-force microscopy investigations for samples with n=0 and 3 reveal that the magnetic-domain-length scale is within the range 800-1500 nm. This is larger than the grain size, indicating the existence of exchange coupling between the hard and soft phase. (C) 1999 Elsevier Science S.A. All rights reserved. |
