This work demonstrates the feasibility of using low-energy Ar ion beam assist bombardment of permalloy (Py=Ni81Fe19) multilayers during growth to selectively manipulate multilayer component coercivity, with minimal degradation of saturation magnetization characteristics. The enhanced giant magnetoresistance characteristics of ion beam sputtered multilayers with thin “Co-dusting” is also reported.
