Abstract
A tunnel-type magnetic detecting element is provided. The tunnel-type magnetic detecting element includes a first ferromagnetic layer; an insulating barrier layer; and a second ferromagnetic layer. The first ferromagnetic layer, the second ferromagnetic layer, or both have a Heusler alloy layer contacting the insulating barrier layer. Equivalent planes represented by {110} surfaces, are preferentially oriented parallel to a film surface in the Heusler alloy layer. The insulating barrier layer is formed of MgO and the equivalent crystal planes represented by the {100} surfaces or the equivalent crystal planes represented by the {110} surfaces are oriented parallel to the film surface.
