    摘要： There is provided a magnetic detecting element having a large ΔRA. A free magnetic layer has a three layer structure in which a CoFe layer, an NiaFeb alloy layer (where a and b are represented by at %, 0≦a≦25, and a+b=100), and a CoFe layer are laminated from the bottom. If the at % of Ni in an NiFe alloy that exists in the free magnetic layer is in this range, a spin-dependent bulk scattering coefficient β increases, and the product ΔRA of the resistance variation of the magnetic detecting element and the area of the element can be made increased.

    摘要： A free magnetic layer is a laminated body of a CO2MnZ alloy layer (Z is one or more elements selected from a group consisting of Al, Sn, In, Sb, Ga, Si, Ge, Pb, and Zn) and a CoaFe100-a alloy layer. The CoaFe100-a alloy layer has a composition ratio 76≦a≦100 or a face-centered cubic (fcc) structure, in which an equivalent crystal face expressed as a {111} plane is preferentially oriented in a direction parallel to a film surface, and the CoaFe100-a alloy layer is in contact with the nonmagnetic material layer.

    摘要： The present invention provides a magnetic detecting element including a pinned magnetic layer and a first antiferromagnetic layer which constitutes an exchange coupling film and the structures of which are optimized for properly pinning magnetization of the pinned magnetic layer, improving reproduction output and properly complying with a narrower gap, and a method of manufacturing the magnetic detecting element. The pinned magnetic layer has a synthetic ferrimagnetic structure, and the first antiferromagnetic layer has a predetermined space C formed at the center in the track width direction to produce exchange coupling magnetic fields only between the first antiferromagnetic layer and both side portions of a first magnetic layer of the pinned magnetic layer. Therefore, the magnetization of the pinned magnetic layer can be pinned, and an improvement in reproduction output and gap narrowing can be realized. Furthermore, a magnetic detecting element with high resistance to electrostatic damage (ESD) can be manufactured. Thus, a magnetic detecting element adaptable for a future higher recording density can be provided.
