Abstract:
Disclosed is a magnetic memory device including a pinned magnetic pattern and a free magnetic pattern that are sequentially stacked on a substrate, a tunnel barrier pattern between the pinned magnetic pattern and the free magnetic pattern, a top electrode on the free magnetic pattern, and a capping pattern between the free magnetic pattern and the top electrode. The capping pattern includes a lower capping pattern, an upper capping pattern between the lower capping pattern and the top electrode, a first non-magnetic pattern between the lower capping pattern and the upper capping pattern, and a second non-magnetic pattern between the first non-magnetic pattern and the upper capping pattern. Each of the lower capping pattern and the upper capping pattern includes a non-magnetic metal. The first non-magnetic pattern and the second non-magnetic pattern include different metals from each other.
