In case of SG or FM clusters embedded in an AFM matrix the MH loop never saturates because of the presence of strong anti ferromagnetic interaction, then how genuine exchange bias property is defined, all can be think of minor loop as we are not getting saturation?
or in that case how we will know the saturating field up to what we should measure the MH loop to avoid the minor loop?
