N2 - The dynamics of antiphase-boundary motion is investigated by the emerging method of x-ray photon correlation spectroscopy. Time correlations of intensity fluctuations from the fundamental (110) and from the superstructure (100) reflection of the B2-ordered Co60Ga40 intermetallic phase are analyzed. By applying detrended fluctuation analysis the observed correlation behavior can be unambiguously attributed to dynamics of antiphase domains. From the temperature dependence an activation energy for this dynamics is derived-in good agreement with results from Monte Carlo simulations. The study underlines the potential of the method for investigations of slow dynamics in hard-condensed matter.
