Spin valve sensor with modified magnetostriction |
摘要 |
A spin valve sensor has a pinned layer structure which includes first, second and third pinned films wherein the first pinned film is nickel iron and is located between the second and third pinned films which are cobalt iron. This structure significantly reduces the magnetostriction of the free layer structure of the spin valve sensor to an acceptable level.
