Abstract:
1. A magnetic memory device comprising: a magnetoresistive element including a fixed layer having a direction of magnetization thereof fixed, a recording layer having a direction of magnetization thereof varied, and a non-magnetic layer interposed between the fixed layer and the recording layer; a first wiring layer extending in a first direction and configured to generate a magnetic field for recording data in the magnetoresistive element; and a second wiring layer extending in a second direction perpendicular to the first direction and configured to generate a magnetic field for recording the data in the magnetoresistive element, wherein the recording layer includes: a base portion extending in a third direction rotated from the first direction by an angle falling within a range of more than 0° to not more than 20°, the base portion including a first side and a second side opposing each other and extending in the third direction, the base portion including a third side and a fourth side opposing each other; and a first projection and a second projection outwardly projecting from a center portion of the first side and a center portion of the second side, respectively, in a fourth direction perpendicular to the third direction, the third side and the fourth side being inclined with respect to the fourth direction in the same rotational direction as a rotational direction in which the third direction is rotated, and the recording layer has a plurality of round corners.
