High temperature annealing mtj
WebAnnealing was carried out in ambient con-ditions with a 40 min ramp up, followed by 10 min at the annealing temperature, and finallya1hcool down. During the thermal treatment, the junctions were submitted to a dc magnetic field of 1.6 k Oe along the easy axis. The MTJ sensors were characterized in a probe station WebApr 2, 2015 · Magnetite (Fe 3 O 4) is an eligible candidate for magnetic tunnel junctions (MTJs) since it shows a high spin polarization at the Fermi level as well as a high Curie temperature of 585°C. In this study, Fe 3 O 4 /MgO/Co-Fe-B MTJs were manufactured.
