Magnetoresistance effect element, magnetic head and magnetic reproducing apparatus |
摘要 |
In a spin valve type element, an interface insertion layer ( 32, 34 ) of a material exhibiting large spin-dependent interface scattering is inserted in a location of a magnetically pinned layer ( 16 ) or a magnetically free layer ( 20 ) closer to a nonmagnetic intermediate layer ( 18 ). A nonmagnetic back layer ( 36 ) may be additionally inserted as an interface not in contact with the nonmagnetic intermediate layer to increase the output by making use of spin-dependent interface scattering along the interface between the pinned layer and the nonmagnetic back layer or between the free layer and the nonmagnetic back layer.
