Abstract
In a spin valve type element, an interface insertion layer () of a material exhibiting large spin-dependent interface scattering is inserted in a location of a magnetically pinned layer () or a magnetically free layer () closer to a nonmagnetic intermediate layer (). A nonmagnetic back layer () 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.
