Abstract:
1. A magnetoresistive element of a CPP type configuration including an antiferromagnetic layer, a fixed magnetic layer, a first non-magnetic layer, a free magnetic layer, and a second non-magnetic layer, the magnetoresistive element comprising: a ferromagnetic junction layer situated between the fixed magnetic layer and the antiferromagnetic layer; a first interface layer situated between the free magnetic layer and the first non-magnetic layer; and a second interface layer situated between the free magnetic layer and the second non-magnetic layer; wherein each of the first interface layer and the second interface layer includes a material mainly having CoNiFe; wherein the ferromagnetic junction layer formed of a ferromagnetic material has a saturation magnetic flux density higher than that of the fixed magnetic layer.
