    摘要: A magnetic detection element capable of maintaining the ΔRA at a high level and reducing the magnetostriction by improving a material for a free magnetic layer, as well as a method for manufacturing the same, is provided. The free magnetic layer includes a laminate composed of a CoMnX alloy layer formed from a metal compound represented by a compositional formula CoaMnbXc (where X represents at least one of Ge, Ga, In, Si, Pb, Zn, and Sb and a+b+c=100 atomic percent) and a CoMnZ alloy layer formed from a metal compound represented by a compositional formula CodMneZf (where Z represents at least one of Sn and Al and d+e+f=100 atomic percent). In this manner, the magnetostriction of the free magnetic layer can be reduced.

    摘要: A magnetic detecting device having a large ΔRA value is provided. A free magnetic layer has a three layer structure in which a CoFe layer, a NiaFeb alloy layer (here, a and b are represented by at %, and satisfy the relationship of 47≦a≦77 and a+b=100), and a CoFe layer are laminated. In addition, pinned magnetic layers have heusler alloy layers, which are made of a heusler alloy such as a Co2MnGe alloy. Accordingly, the product ΔRA of a magnetic resistance variation ΔR of the magnetic detecting device and an area A of the device can have a value of 5 mΩμm2 or more.

    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 magnetic sensing element is described, including a multilayer film including a pinned magnetic layer, a free magnetic layer disposed on the pinned magnetic layer with a nonmagnetic layer therebetween, wherein a current flows perpendicular to the surfaces of the individual layers of the multilayer film. The nonmagnetic layer is composed of Cu and has a face-centered cubic lattice crystal structure in which the {111} planes are preferentially oriented in a direction parallel to the surfaces of the layer. At least one of the pinned magnetic layer and the free magnetic layer includes a Co2Mn(Ge1-xSnx) alloy layer, the subscript x satisfying the range of 0.2≦x≦0.8; and the Co2Mn(Ge1-xSnx) alloy layer has a body-centered cubic lattice crystal structure in which the {110} planes are preferentially oriented in a direction parallel to the surfaces of the layer.
