N2 - We report on magnetic, resistivity, Mössbauer spectroscopy, and scanning tunneling spectroscopy studies of ceramic superconducting (SC) and non-SC Ru Sr2 Y1.5 Ce0.5 Cu2 O10-δ (x=0.5) and Ru Sr2 YCe Cu2 O10 (x=1). All materials studied were prepared at high oxygen pressure under the same conditions. Two magnetic transitions at T2M and TM (T2M < TM) are observed. For the SC x=0.5 material, both T2M and TM 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 TM.
