Abstract: <P>PROBLEM TO BE SOLVED: To reduce ion-beam damage in a magnetoresistance-effect element while realizing a resistance decrease by removing a surface oxide film to resultantly improve characteristics of the element.  <P>SOLUTION: A magnetoresistance-effect layer comprises a tunnel-barrier layer 26, which is interposed by a pinned layer 25 in the lower side and a free layer 27 in the upper side. A non-magnetic layer 28, which is a protective film, is formed on the free layer 27. A double-layer film consisting of layers 35a, 35b is formed on the opposite side (-Y side) of an air bearing surface so as not to overlap the effective area that effectively participates in magnetic detection by the magnetoresistance-effect layer but to touch the effective area. The lower layer 35a is composed of an insulating material. The upper layer 35b is composed of a material containing at least one kind of the elements, each of which has a larger atomic weight than that of Si. The layers 35a, 35b do not constitute a magnetic-domain control layer that gives a biased magnetic field to the free layer 27.  <P>COPYRIGHT: (C)2004,JPO
