Abstract:
1. A magnetic device comprising: a first group and a second group of nanoholes formed in an alumina film through anodic oxidation, each of the first group of nanoholes contains at least alternately stacked magnetic and nonmagnetic layers; and each of the second group of nanoholes contains at least a conductive material forming a non-magnetic nanowire, wherein the first and second groups of nanoholes are arranged in an alternating manner with two of the second group of nanoholes being positioned immediately adjacent to and on opposite sides of one of the first group of nanoholes, and the non-magnetic nanowires in the two of the second group of nanoholes serve together as a writing wire for writing into the magnetic layers in the one of the first group of nanoholes.
