Abstract
Embodiments of the present invention provides sufficiently high exchange coupling with a magnetic layer and improve the yield and reliability of a magnetoresistive head. By using a tilted growth crystalline structured antiferromagnetic film manufactured by an oblique incident deposition method, a high exchange coupling field with a ferromagnetic film can be obtained. As a result, excellent reliability and high output can be obtained in a magnetoresistive head utilizing features in accordance with embodiments of the present invention.
