Spectral character of dielectric response in CaCu3Ti4O12 across 0.5Hz-4MHzover 45-200K corresponding to neither the Debyean nor the KWW relaxationpatterns rather indicates a random-walk like diffusive dynamics of moments.Non-linear relaxation here is due to the many body dipole-interactions, asconfirmed by spectral-fits of our measured permittivity to the Dissado-Hillbehaviour. Fractional power-laws observed in {\epsilon}*({\omega})macroscopically reflect the fractal microscopic configurations. Below ~100K,the power-law exponent m (n) steeply decreases (increases), indicating finitelength-scale collective response of moment-bearing entities. At highertemperatures, m gradually approaches 1 and n falls to low values, reflectingtendency towards the single-particle/Debyean relaxation.
