  • Patent number: 7419729
    Abstract: A multilayered ferromagnetic laminate includes a first magnetic film having a cobalt alloy and a second magnetic film having an iron-nitrogen alloy. The films are deposited upon one another and laminated to provide a multilayered film structure having an alternating plurality of the first and second magnetic films. The cobalt alloy may be a cobalt-zirconium-tantalum alloy. The nitrogen is incorporated interstitially in the crystalline structure of the iron of the second magnetic film. The laminate forms the magnetic shields and the write poles of magnetic disk and tape heads. The lamination of the first magnetic film which has high electrically resistive, high mechanical hardness, and high magnetic moment characteristics with the second magnetic film which has lower electrically resistive and very high magnetic moment characteristics yields the laminate which has very high magnetic moment and very hard pole material characteristics and has the ability to write at high frequencies.
