Abstract:
A magnetoresistive element, comprising:a first ferromagnetic layer element; a second ferromagnetic layer element; and a non-magnetic layer element disposed between said first ferromagnetic layer element and said second ferromagnetic layer element; said non-magnetic layer element containing a material exhibiting a diffusion barrier effect in a temperature range between 20Â° C. and 450Â° C. and being substantially non-diffusible into said first and second ferromagnetic layer elements; said layer elements being produced by a semiconductor processing technique; and said non-magnetic layer element containing a material selected from the group consisting of at least one of the elements selected from the group consisting of Ti, W, Mo; a nitride of the elements selected from the group consisting of Ti, W, and Mo; a silicide of the elements selected from the group consisting of Ti, Ta, W, and Mo; a boride of the elements selected from the group consisting of Ti, Ta, W, and Mo; and an alloy of at least two elements selected from the group consisting of Ti, Ta, W, and Mo.
