Abstract
An example magnetoresistive effect element includes a magnetoresistive effect film including a magnetization pinned layer, a magnetization free layer, and an intermediate layer interposed therebetween and having a magnetic region and a nonmagnetic region whose electrical resistance is higher than the magnetic region. A sense current is passed to the magnetoresistive effect film in a direction substantially perpendicular to the film plane thereof. The magnetic region of the intermediate layer penetrates the nonmagnetic region locally and extends in the direction substantially perpendicular to the film plane. The nonmagnetic region contains a nonmagnetic metallic element having a larger surface energy than a magnetic metallic element contained in the magnetic region.
