Description	Journal: Journal of Physics D: Applied Physics The occurrence of both interlayer exchange coupling and perpendicular magnetic anisotropy is evidenced in Pt/Co/Ir/Co/Pt magnetron sputtered structures. We point out the effect of lattice strains on stabilizing the perpendicular magnetic anisotropy. The surface magnetic anisotropy constant is around 1.76 erg/cm2 and around 1.5 erg/cm2 for the Co layers, depending on their positioning within the stack. We demonstrate a relatively high interlayer exchange constant of -2.5 erg/cm2 at the first antiferromagnetic coupling maximum corresponding to an exchange field larger than 12 kOe. The interlayer exchange coupling shows remarkable annealing endurance being preserved for annealing temperatures up to 400 °C.
