Claim Text:
1. A magnetic memory device, comprising: a substrate; a plurality of first electrodes on a first plane on the substrate; a plurality of second electrodes on a second plane that is different from the first plane; and a magnetic tunnel junction (MTJ) structure between the plurality of first electrodes and the plurality of second electrodes, the MTJ structure including a first magnetic layer, a tunnel barrier layer and a second magnetic layer that are sequentially stacked on the plurality of first electrodes, and at least one of the first magnetic layer or the second magnetic layer including: wherein the one of the plurality of first electrodes comprises a first one of the plurality of first electrodes, and the ones of the plurality of magnetic material patterns comprise first ones of the plurality of magnetic material patterns that overlap with the first one of the plurality of first electrodes in plan view, wherein the plurality of first electrodes comprise a second one of the plurality of first electrodes, and the plurality of magnetic material patterns comprise second ones of the plurality of magnetic material patterns that overlap with the second one of the plurality of first electrodes in plan view, and wherein the plurality of magnetic material patterns comprise third ones of the plurality of magnetic material patterns that are between the first ones of the plurality of magnetic material patterns and the second ones of the plurality of magnetic material patterns.
