a–d K1 as a function of ΔW (a), χ (b), ξ (c), and ΔWmeas (d) for Pt/Co/X stacks with various X elements. e–h Correlation results for K2, similar to those shown in (a–d). The values of ΔW, χ, and ξ were taken from the literature27,28,29, and those of ΔWmeas were obtained in this study via UPS measurements. The error bars of K1, K2, and ΔWmeas were obtained from three repeated measurements, whereas those of ΔW represent the standard deviations of reported values.
