Abstract
⺠We measure the magnetization reversal of individual nm small Co island by spin-STM. ⺠We identify an inhomogeneous magnetic anisotropy within a single Co island. ⺠The magnetic anisotropy near the rim is negligible as compared to 0.148 meV/atom at the island center. ⺠A crossover of the magnetization reversal from an exchange-spring behavior to domain wall formation is suggested. ⺠The impact of the observed spatial variation of the spin-dependent electronic properties on reversal is discussed.
