Abstract
A spin-valve magnetic transducing element. In one embodiment, a spin-valve magnetic transducing element is disclosed in which a ferromagnetic tunneling junction film, including first and second ferromagnetic layers and an insulating layer is enclosed between the ferromagnetic layers. A nonmagnetic metal thin film is inserted between the second ferromagnetic layer and the insulating layer, all of which are formed on a substrate.
