Hard magnetic material |
| 摘要 |
Bulk hardened magnetic materials with compositions expressed by a general formula SmuCe1-u(Co1-x-yFexCuy)z are provided. Compositions in the limited range of 0.3</=u</=1.0, 0</=x</=0.1, 0.09</=y</=0.18, 6.0</=z</=7.5 lead to magnetic materials with unexpectedly large maximum energy product and with a newly found two phase structure. Magnetic materials with maximum energy product of over 13 MG.Oe (megagauss) oersted), residual induction over 7000 G and intrinsic coercive force over 3000 Oe are obtained by subjecting the compositions to a sintering process.
