description The effects of device shape and size on the giant magnetoresistive (MR) response of NiFe/sub 7.5 nm//Co/sub 0.6 nm//Cu/sub 3 nm//Co/sub 0.6 nm//NiFe/sub 7.5 nm//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 /spl mu/m to 1.5 /spl mu/m are simulated. The effects of the magnetostatic coupling between the magnetic layers and their self-demagnetization are studied.
