N2 - An unusual thermal-magnetic hysteresis was observed between a minor magnetic transition around 120 K and the main one at 80 K in superconducting (formula presented) (Ru1222R) samples, where (formula presented) or Eu, down to a submicron length scale. The observation suggests a possible phase separation and is consistent with the very small but universal demagnetizing factor observed, which is difficult to reconcile with the canted-spin structure previously proposed. In such a scenario, the unusual superconducting properties of the Ru-based cuprates can also be understood naturally.
