“…Nevertheless, the values of H C and H EB are increased compared to as deposited case.Variation of H EB as a function of the AFM or buffer layer thickness are similar, where one cannot observe a spontaneous EB until a peak value of coercive field. After a reduction in H C , H EB is obtained.Such kind of correlation between H C and H EB with respect to thickness of AFM layer was also reported for CoPt/IrMn system[15,23]. In our study, both increasing t Pt and t AFM improved AFM ordering and exchange coupling in the interfaces and hence enhanced H EB and H C values.…”
