Manufacturing method for magnetoresistive head having an antiferromagnetic layer of PTMN |
摘要 |
The present invention provides a magnetoresistive head wherein: a magnetoresistive film is created in a read-track region at the center of the magnetoresistive head; an antiferromagnetic film and a ferromagnetic film experiencing an exchange coupling magnetic field due to direct contact with the antiferromagnetic film are created on each end of the magnetoresistive film outside the read-track region in such a way that the ferromagnetic film is located beside the magnetoresistive film; a nonmagnetic intermediate film is created between the magnetoresistive film and the ferromagnetic film for preventing ferromagnetic coupling from being developed on a contact boundary surface between the magnetoresistive film and the ferromagnetic film and for making crystal orientations of the antiferromagnetic film and the ferromagnetic film uniform; and bias magnetization is applied to the magnetoresistive film by exchange coupling between the antiferromagnetic film and the ferromagnetic film.
