Abstract:
A magnetic memory device includes a reference magnetic structure, a free magnetic structure, and a tunnel barrier pattern between the reference magnetic structure and the free magnetic structure. The reference magnetic structure includes a first pinned pattern, a second pinned pattern between the first pinned pattern and the tunnel barrier pattern, and an exchange coupling pattern between the first and the second pinned pattern. The second pinned pattern includes a first magnetic pattern adjacent the exchange coupling pattern, a second magnetic pattern adjacent the tunnel barrier pattern, a third magnetic pattern between the first and the second magnetic pattern, a first non-magnetic pattern between the first and the third magnetic pattern, and a second non-magnetic pattern between the second and the third magnetic pattern. The first non-magnetic pattern has a different crystal structure from the second non-magnetic pattern, and at least a portion of the third magnetic pattern is amorphous.

Claim (Index 1):
A magnetic memory device, comprising:\n a reference magnetic structure and a free magnetic structure on a substrate; and a tunnel barrier pattern between the reference magnetic structure and the free magnetic structure, wherein the reference magnetic structure comprises: a first pinned pattern; a second pinned pattern between the first pinned pattern and the tunnel barrier pattern; and an exchange coupling pattern between the first pinned pattern and the second pinned pattern, wherein the second pinned pattern comprises: a first magnetic pattern adjacent the exchange coupling pattern; a second magnetic pattern adjacent the tunnel barrier pattern; a third magnetic pattern between the first magnetic pattern and the second magnetic pattern; a first non-magnetic pattern between the first magnetic pattern and the third magnetic pattern; and a second non-magnetic pattern between the second magnetic pattern and the third magnetic pattern, and wherein the first magnetic pattern has a hexagonal close-packed (HCP) crystal structure or a face centered cubic (FCC) crystal structure, and a (0001) plane of the first magnetic pattern having the hexagonal close-packed (HCP) crystal structure, or a (111) plane of the first magnetic pattern having the face centered cubic (FCC) crystal structure is parallel to a top surface of the substrate.
