  We present the results from a magnetization, structural, and nuclear
quadrupole resonance study of the ruthenate-cuprate, RuSr2R2-xCexCu2O10+d with
x=1 and R=Eu. This compound is a superconductor for Ce doping in the range
0.4<=x<=0.8 and displays ferromagnetic order for 0.4<=x<=1.0. We show that the
tilting and rotation of the RuO6 octahedra are essentially the same for x=1,
x=0.6 and the superconducting antiferromagnet, RuSr2GdCu2O8. However, the
moment per Ru in RuSr2EuCeCu2O10+d is comparable to that observed in
RuSr2EuCu2O8. These results indicate that it is unlikely that the different
magnetic order found in RuSr2R2-xCexCu2O10+d and RuSr2RCu2O8 (R=Y,Gd,Eu) is due
to changes in structurally induced distortions of the RuO6 octahedra as found
in the ruthenate compounds (e.g. Sr1-xCaxRuO3). We show that the Cu nuclear
quadrupole resonance (NQR) data are similar to those observed in the single
CuO2 layer superconductor, La1-xSrxCuO4, where the Cu spin-lattice relaxation
rate is dominated by hyperfine coupling within the CuO2 layers and any
additional hyperfine coupling from spin fluctuations in the RuO2 layers is
small.
