摘要：

We report on magnetic, resistivity, Mossbauer spectroscopy, and scanning tunneling spectroscopy studies of ceramic superconducting (SC) and non-SC RuSr2Y1.5Ce0.5Cu2O10-delta (x=0.5) and RuSr2YCeCu2O10 (x=1). All materials studied were prepared at high oxygen pressure under the same conditions. Two magnetic transitions at T-2M and T-M (T-2M < T-M) are observed. For the SC x=0.5 material, both T-2M and T-M and saturation moments are lower, but its coercive fields are higher as compared to the non-SC x=0.5 sample material. In the x=1 sample, a dramatic increase in the magnetoresistance occurs at T-M.
