Abstract
We have synthesized (Ti,Cu)Sr{sub 2}(RE{sub 0.8}Ce{sub 0.2}){sub 2}Cu{sub 2}O{sub 10-{delta}} (RE=Sm, Eu, and Gd). Powder X-ray diffraction indicated that the average crystal structure of these samples has a body-centered tetragonal 1222 structure with space group I4/mmm, and these samples contained SrTiO{sub 3} and CeO{sub 2} impurities. The lattice parameters of (Ti,Cu)Sr{sub 2}(RE{sub 0.8}Ce{sub 0.2}){sub 2}Cu{sub 2}O{sub 10-{delta}} are a=0.38516(5) nm and c=2.8314(4) nm for RE=Sm, a=0.38536(2) nm and c=2.8389(2) nm for RE=Eu, and a=0.38456(3) nm and c=2.83566(5) nm for RE=Gd. The superconducting transitions were observed for RE=Eu (T{sub c}=20 K) and Sm (T{sub c}=25 K) samples in the electrical resistivity and magnetic susceptibility measurements.
