<p>A MAGNETORESISTANCE EFFECT ELEMENT IS PROVIDED WITH A LAMINATED FILM WHICH IS COMPOSED OF A FIRST FERROMAGNETIC CONDUCTIVE LAYER, A NON-MAGNETIC CONDUCTIVE LAYER SUPERPOSED ON THE FIRST FERROMAGNETIC FILM, AND A SECOND FERROMAGNETIC CONDUCTIVE LAYER SUPERPOSED ON THE NON-MAGNETIC CONDUCTOR LAYER, AND WHICH IS PROVIDED WITH A PAIR OF ELECTRODES FORMED ON THE LAMINATED FILM, WHEREIN AT LEAST ONE OF THE FIRST AND SECOND MAGNETIC CONDUCTIVE LAYERS COMPRISES AT LEAST A FIRST FERROMAGNETIC LAYER AND A SECOND FERROMAGNETIC FILM, FOR EXAMPLE, CO ALLOY FILMS WHOSE DIRECTIONS OF AXIS OF EASY MAGNETIZATION ARE DIFFERENT FROM EACH OTHER. FURTHERMORE, THIS ELEMENT IS A MAGNETORESISTANCE EFFECT ELEMENT PROVIDED WITH A SPIN VALVE FILM HAVING A NON-MAGNETIC LAYER DISPOSED BETWEEN A FIRST MAGNETIC LAYER COMPOSED OF A LAMINATED FILM OF SUCH A FERROMAGNETIC FILM AS A CO BASED MAGNETIC ALLOY AND A SOFT MAGNETIC LAYER, AND A SECOND MAGNETIC LAYER, WHEREIN THE SOFT MAGNETIC LAYER IS COMPOSED OF A SOFT MAGNETIC MATERIAL LAMINATED FILM OF A SOFT MAGNETIC MATERIAL FILM OF ONE KIND OR SOFT MAGNETIC MATERIAL FILMS OF TWO OR MORE KINDS, AND VALUES OF THEIR MAGNETIZATION MS(T), FILM THICKNESS D (NM), AND ANISOTROPIC MAGNETIC FIELD HK (OE) SATISFY ( )(MS X D X HK) > 30 (TNM OE).</p> |
