According to one embodiment, a magnetic memory device includes a conductive member, a first magnetic layer, a second magnetic layer, and a first nonmagnetic layer. The conductive member includes a first layer. The first layer includes at least one selected from the group consisting of HfN having a NaCl structure, HfN having a fcc structure, and HfC having a NaCl structure. The first magnetic layer is separated from the first layer in a first direction. The second magnetic layer is provided between the first layer and the first magnetic layer. The first nonmagnetic layer is provided between the first magnetic layer and the second magnetic layer.
