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