Abstract :
The growth and crystallization processes of Co20Fe50B30/MgO/Co20Fe50B30 magnetic tunnel junction structures are investigated with 2θ x-ray diffraction. By increasing thickness and proper annealing, the crystal structure of MgO has been improved. The results show important information for preparation of magnetic tunnel junction.
