Highly (001)-textured Mn-Ga polycrystalline ultrathin films with a perpendicular magnetic anisotropy

Perpendicularly magnetized ultrathin films of magnetic metals are technologically important for various spintronic applications, such as the free layer in magnetic tunnel junctions (MTJs) for the spin-transfer-torque (STT) magnetoresisive random access memory (MRAM) and in current-perpendicular magnetoresisive devices for the spin-torque radio frequency (rf) oscillators and detectors.
