Claim 0:
1. A magnetoresistive element comprising:
a magnetic reference layer having a reference layer magnetization fixed in a direction perpendicular to the magnetic reference layer;
a tunnel barrier layer provided on a surface of the reference layer;
a magnetic recording layer provided on a surface of the tunnel barrier layer, which is opposite to a surface of the tunnel barrier layer where the magnetic reference layer is provided, and having a recording layer magnetization that is perpendicular to the magnetic recording layer and is changeable relative to the reference layer magnetization;
a nonmagnetic nano-current-channel (NCC) structure provided on a surface of the magnetic recording layer, which is opposite to a surface of the magnetic recording layer where the tunnel barrier layer is provided, and comprising a spatial distribution of perpendicular conducting channels throughout the NCC structure thickness and surrounded by an insulating medium; and
a cap layer provided on a surface of the NCC structure, which is opposite to a surface of the NCC structure where the magnetic recording layer is provided;
wherein said tunnel barrier layer has a first resistance-area product (RA1), each of said perpendicular conducting channels is electrically conductive in a perpendicular direction between said magnetic recording layer and said cap layer and has a second resistance-area product (RA2), said insulating medium comprises at least one oxide layer and is less electrically conductive in a perpendicular direction between said magnetic recording layer and said cap layer than each of said perpendicular conducting channels and has a third resistance-area product (RA3), and said magnetic recording layer has channeled regions which directly contact said perpendicular conducting channels of said NCC structure, and non-channeled regions which directly contact said insulating medium of said NCC structure, wherein each of said channeled regions of said magnetic recording layer has a lower perpendicular magnetic anisotropy (PMA) than said non-channeled regions of said magnetic recording layer.
