Read head having spin valve sensor with improved capping layer |
| 摘要 |
A capping layer including thin films of ruthenium (Ru) and a metallic oxide are employed with a spin valve sensor for maintaining the MR coefficient (dr/R) of the spin valve sensor after being subjected to annealing steps which simulate hard balance of the photoresist layers in the insulation stack of a write head.
