Heusler alloy based current-perpendicular-to-the-plane giant magnetoresistance heads for high density magnetic recording

Abstract

Narrow-track current-perpendicular-to-the-plane giant magnetoresistive heads containing Heusler alloy layer have been fabricated utilizing an abutted junction hard bias design. The head performance has been tested quasistatically and dynamically under high density recording conditions using a perpendicular magnetic recording media.
