Morphology and domain wall propagation in Au/Co/Au deposited on different substrates

► We interpreted the results using a simplified form of Fatuzzo-Labrune model. ► The wall movement is associated with a β exponent. ► The reversal by domain wall propagation corresponds to 1.3<β≤3. ► The β value allows distinguishing between different movements of wall. ► Wall movement is correlated with morphologic properties.
