| Title: |
400-Fold Reduction in Saturation Field by Interlayering |
| Published: |
January 13, 2009 |
| Abstract: |
The buildup of stress with increasing thickness of magnetic thin films is a common phenomenon that often induces undesirable saturation fields that can convert an otherwise magnetically soft film into a magnetically hard one. We have found that by interlayering such a magnetic thin film with films that are either not lattice matched or have a different crystal structure, reductions in the saturation field as large as 400 fold can be achieved. Stress relief by grain re-nucleation on the intelayers appears to be responsible. |
