摘要
The effects of device shape and size on the giant magnetoresistive (MR) response of NiFe7.5nm/Co-0.6nm/Cu-3nm/Co-0.6nm/NiFe7.5nm/FeMn spin-valve magnetoresistive random access memory (MRAM) stripes are studied by micromagnetic simulation, Samples having aspect ratios of 10:1, 3:1 and 1.5:1, and line widths varying from 0.5 mu m to 1.5 mu m are simulated. The effects of the magnetostatic coupling between the magnetic layers and their self-demagnetization are studied.
