Abstract
The CPPGMR element of the present invention has an orientation layerformed on a substrateto texture a Heusler alloy into a (100) direction, an underlying layerthat is an electrode for magneto-resistance measurement stacked on the orientation layer, a lower ferromagnetic layerand an upper ferromagnetic layereach stacked on the underlying layerand made of a Heusler alloy, a spacer layersandwiched between the lower ferromagnetic layersand the upper ferromagnetic layers, and a cap layerstacked on the upper ferromagnetic layerfor surface-protection. This manner makes it possible to provide, inexpensively, an element using a current-perpendicular-to-plane giant magneto-resistance effect (CPPGMR) of a thin film having a trilayered structure of a ferromagnetic metal/a nonmagnetic metal/a ferromagnetic metal, thereby showing excellent performances.
