Abstract
The invention comprises a novel composite seed layer with lattice-matched crystalline structure so that an excellent epitaxial growth of magnetic pinning layer along its FCC (111) orientation can be achieved, resulting in a significant enhancement of PMA for perpendicular spin-transfer-torque magnetic-random-access memory (pSTT-MRAM) using perpendicular magnetoresistive elements as basic memory cells which potentially replace the conventional semiconductor memory used in electronic chips, especially mobile chips for power saving and non-volatility.
