We studied magnetization and ESR on RuSr2R1.4Ce0.6Cu2O10 (Ru1222; R = Gd, Eu). A ferromagnetic hysteresis in M-H curves is observed below T-M = 180 K. The saturation moment is smaller than that for the expected Ru5+. These results suggest that Ru1222 is weak ferromagnetic. Interestingly, an enhancement in M observed at 100 K is more substantial than that observed at T-M. ESR measurements confirm that this anomalous behavior originates from a change in the Ru moment.
