摘要
An unusual thermal-magnetic hysteresis was observed between a minor magnetic transition around 120 K and the main one at 80 K in superconducting RuSr2(R,Ce)2Cu2O10-δ (Ru1222R) samples, where R=Gd 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.
