A magnetic memory device is provided. The magnetic memory device includes: (i) a cylindrical core, (ii) a metallic buffer layer that surrounds the cylindrical core, (iii) a first ferromagnetic layer that surrounds the metallic buffer layer, (iv) a barrier layer that surrounds the first ferromagnetic layer, and (v) a second ferromagnetic layer that surrounds the barrier layer. The cylindrical core, the metallic buffer layer, the first ferromagnetic layer, the barrier layer, and the second ferromagnetic layer collectively form a magnetic tunnel junction. |
