| 抄録 | In order to understand the coercivity mechanism of Nd-Fe-B magnets, we have investigated the effect of Dy/ Cy cap layers for Nd-Fe-B thin films after heat treatment. Remarkable enhancement of the coercivity was obtained for the Nd-Fe-B thin films prepared at 520 C followed by the post annealing at 625 C. Especially, the value of HC was changed from 5.7 kOe to 25.0 kOe for Nd-Fe-B (100 nm)/ Dy (4 nm)/ Cu (2 nm) thin film. This result suggests that the volume fraction of Dy and Cu layers is close to a eutectic composition of binary Dy-Cu alloys, and Dy is thought to infiltrate into both Nd2Fe14B phase and grain boundary phase. |
