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. (© 2006 WILEY‐VCH Verlag GmbH & Co.
