N2 - We report ac susceptibility data on (formula presented) (Ru-1222, Ce content (formula presented) and 1.0), (formula presented) (Ru-1212), and (formula presented) Both Ru-1222 (formula presented) 1.0) sample types exhibit unexpected magnetic dynamics in low magnetic fields: logarithmic time relaxation, switching behavior, and “inverted” hysteresis loops. Neither Ru-1212 nor (formula presented) exhibit such magnetic dynamics. The results are interpreted as evidence of the complex magnetic order in Ru-1222. We propose a specific multilayer model to explain the data, and note that superconductivity in the ruthenocuprate is compatible with both the presence and absence of the magnetic dynamics.
