dc.descriptionThe effect of nonmagnetic metal additives in metallic antiferromagnets (AFMs) on the exchange bias (EB) has been investigated from a structural, magnetic and Monte Carlo simulation point of view in bilayers of CoFe/IrMn:Cu. Dilution by Cu atoms throughout the volume of the AFM IrMn give rise to an enhanced EB field for temperatures between 5 K and 300 K. The thermoremanent magnetization of the AFM-only is also enhanced with dilution, shows qualitatively the same temperature dependence as EB field and is at the origin of the EB mechanism. Monte Carlo simulations based on a Heisenberg model and temperature dependent uncompensated AFM moments confirm well the experimental results.
