摘要： A magneto-resistance effect element comprising a spin valve film including a first magnetic layer, a second magnetic layer and a non-magnetic layer interposed between the first magnetic layer and the second magnetic layer. Among the first and the second magnetic layers, in at least one of the magnetic layers, close-packed faces of crystal grains which constitute the magnetic layer are isotropically dispersed. Such a magnetic layer, by setting a film thickness of an under layer having an identical crystal structure with the magnetic layer at 2.0 nm or less and by dispersing isotropically close-packed faces of crystal grains constituting the under layer, can be obtained with reproducibility. According to a magneto-resistance effect element comprising such a spin valve film, while maintaining a large MR change rate, for example, magnetostriction constant can satisfy such a low magnetostriction as 1.times.10.sup.-6 or less. Further, excellent soft magnetic property can be provided.

摘要： A magnetoresistance effect element includes a nonmagnetic spacer layer, first and second ferromagnetic layer separated by the nonmagnetic spacer layer, and a nonmagnetic conductivity layer. The first ferromagnetic layer has a magnetization direction at an angle relative to a magnetization direction of the second ferromagnetic layer at zero applied magnetic field. The second ferromagnetic layer has first and second ferromagnetic films antiferromagnetically coupled to one another and an antiferromagnetically coupling film located between and in contact with the first and second ferromagnetic films. The magnetization of the first ferromagnetic layer freely rotates in a magnetic field signal. The nonmagnetic conductivity layer is disposed in contact with the first ferromagnetic layer so that the first ferromagnetic layer is disposed between the nonmagnetic high-conductivity layer and the nonmagnetic spacer layer. The first ferromagnetic layer has a film thickness between 0.5 nanometers and 4.5 nanometers.
