Logarithmic values of hTST prefactors plotted against their corresponding energy barriers for Fe, Ni, and Cr. (top) All the possible events from the simulations are included, with compensation effects determined via linear fits to events with barriers above 0.3 eV, yielding slopes of −0.587(0.006) eV⁻¹ (Fe), −0.070(0.002) eV⁻¹ (Ni), and 0.017(0.004) eV⁻¹ (Cr). (bottom) A curated subset of selected events above 0.3 eV shows compensation slopes of 0.47(0.02) eV⁻¹, 0.49(0.02) eV⁻¹, and 1.29(0.04) eV⁻¹ for Fe, Ni, and Cr, respectively. Values in parentheses represent the standard deviation of the linear fit [48].
