Magnetostriction curves with (111) textured polycrystalline Co/Pd mult
ilayers, as deposited or submitted to Ar+ ion implantation or thermal
annealing, are presented and discussed. Both treatments, while promoti
ng intermixing among Co and Pd atoms, induce an increase in the satura
tion magnetostriction values. The evolution of the engineering curves,
however, are different due to different structural modifications prom
oted by the two treatments.
