Abstract

New features of the magnetization reversal of a patterned bilayer in the form of a square mesh consisting of 16 um wide intersecting stripes of Ni(sub79)Fe(sub21) (30 nm) exchange-coupled with IrMn (10 um) on top were revealed via use of the advanced magneto-optical indicator film technique. A peculiar asymmetry of the remagnetization behavior was observed for the forward and backward branches of the hysteresis loop for fields parallel to the sample's undirectional anisotropy. Herein, we compare the magnetization reversal processes in the biased and nonbiased patterened ferromagnetic nano-layers.
