a Experimental hysteresis curves for Co/C60, Co/Gaq3 and reference Co/Al, Co/CoOx systems measured at 150 K, showing the broadening of the loops for Co interfaced with molecular species. b Theoretical hysteresis curves obtained with the correlated random anisotropy model for KR = 50KU and different correlation radius values.
