A detailed study of the magnetization reversal process in [20 Å Pt/t Å Co]3/100 Å IrMn/20 Å Pt multilayers with 4 Å ≤ t ≤ 9 Å is presented. The hysteresis of as-deposited films with t ≥ 5 Å is found to be asymmetric. This asymmetry is explained by a lateral variation in the perpendicular exchange bias direction due to the growth of IrMn onto multi-domain Co/Pt multilayers.
