Abstract:
1. A magnetoresistive element, comprising: a first ferromagnetic layer a magnetization direction of which is pinned; a second ferromagnetic layer a magnetization direction of which is changed depending on an external magnetic field; an intermediate layer arranged between the first ferromagnetic layer and the second ferromagnetic layer and comprising an insulating layer and a magnetic conductive column, an alloy layer formed between the magnetic conductive column in the intermediate layer and the second ferromagnetic layer and comprising at least one of FeCoAl and FeCoAlCu, and a pair of electrodes configured to supply a current perpendicularly to a film plane of a stacked film comprising the first ferromagnetic layer, the intermediate layer, the alloy layer and the second ferromagnetic layer.
