Effect of O2 partial pressure on magnetic properties of alloys Co-rich nanocrystalline thin films |
| 초록 |
Amorphous alloys of Co-rich magnetic amorphous films are well known as typical soft magnetic alloys. They are used for many kinds of electric and electronic parts such as magnetic recording heads, transformers and inductors. In order to get superior soft magnetic properties of the CoFe-based nanocrystalline thin films, the Co-Fe-Hf-O nanocrystalline thin films have been investigated. These films exhibit excellent soft-magnetic properties: saturation magnetization (4ΠMs) of 16-19 kG, magnetic coercivity (Hc) of 0.1-1Oe, anisotropy field (Hk) of 10-20 Oe, and an electrical property is also shown to be as high as 500 µΩcm. The combination of high 4pMs and relatively high Hk in these films are believed to be partly responsible for the excellent ultra-high-frequency behavior. The soft magnetic properties and electrical property of these films show a dependence on the partial pressure of reactive gas, which presumably changes the microstructure of the films and related magnetic anisotropy. |
