Method and system for providing a magnetic transducer having improved shield-to-shield spacing |
摘要 |
A method and system for providing a magnetic transducer is described. The method and system include providing a magnetic structural barrier layer and a crystalline magnetic layer on the magnetic structural barrier layer. The magnetic structural barrier layer may reside on a shield. The method and system also include providing a nonmagnetic layer on the crystalline magnetic layer. A pinning layer is provided on the nonmagnetic layer. Similarly, a pinned layer is provided on the pinning layer. The pinning layer is magnetically coupled with the pinned layer. The method and system also include providing a free layer and a nonmagnetic spacer layer between the pinned layer and the free layer. |

1. A magnetic structure comprising:
a magnetic shield layer; a magnetic structural barrier layer on the magnetic shield layer, the magnetic structural barrier layer being amorphous as-deposited but at least partially crystalline after fabrication of the completed magnetic structure; a crystalline magnetic layer on the magnetic structural barrier layer, the magnetic structural barrier layer breaking a crystal structure coupling between the magnetic shield layer and the crystalline magnetic layer; a nonmagnetic layer on the crystalline magnetic layer; a pinning layer on the nonmagnetic layer; a pinned layer on the pinning layer, the pinning layer being magnetically coupled with the pinned layer; a free layer; and a nonmagnetic spacer layer between the pinned layer and the free layer. |
