Abstract:
A magnetoresistive effective type element, comprising:a magnetoresistive effective film; a first shielding film of which one main surface is adjacent to one main surface of said magnetoresistive effective film; a second shielding film of which one main surface is adjacent to the other main surface of said magnetoresistive effective film; and a third shielding film of which one main surface is adjacent to the other main surface of said first shielding film or said second shielding film opposite to said magnetoresistive effective film, wherein said first shielding film and said second shielding film function as current-supplying layers to flow current perpendicular to and through said magnetoresistive effective film, and wherein said first shielding film and said second shielding film are made of at least one selected from the group consisting of NiFe, CoZrTa, FeN, FeAISi, NiFe alloy, Co-based amorphous material and Fe-based soft magnetic material.
