Junction area dependence of tunneling magnetoresistance

Description

Spin dependent tunneling devices Ta/NiFe/Ta/NiFe/FeMn/NiFe/CoFe/Al2O3/CoFe/NiFe/Al with in-situ naturally oxidized Al2O3 barrier were fabricated using ion beam deposition and DC sputtering. The as-deposited and post-annealing junctions showed tunneling magnetoresistance of 8-18% with resistance-area products (RxA) of 340-60 Ω μm2, which were dependent on the junction area (81-4 μm2)
