  In this letter we present emergent screening of magnetic monopole and dipole
by the presence of 20nm aluminum cover layer. Our results were obtained in base
of magnetic atomic force measurements, performed after external magnetic field
steps application. We show that the evolution of magnetization and monopole
population is affected by the aluminum presence and attribute that phenomena to
the proximity effect, which is responsible for the magnetization vanish of the
firstatomic layers at the interface. Using experimental values to estimate the
decrease in the nano-magnetic dipole value used in an emergent excitation model
and in the switching field distribution heterogeneity used in simulations, we
observe a very good agreement among experimental and simulation results. The
presented emergent screening could be used in new ASI geometries for
thermodynamic activation or proposition of devices with selective magnetic
monopole mobility.
