We have discovered new members of the Pb-based 1222 layered cuprates containing sulfur of (Pb0.75S0.25)Sr2(RE1.6Ce0.4)Cu2Oz with RE = Sm, Gd, Dy, and Ho. All the samples are of almost-single 1222 phase. From the ρ–T and χ–T measurements, they a

Thin films of the perovskite Gd0.5Sr0.5CoO3 (GSCO), a cathode material, were fabricated by pulsed laser deposition methods. Two kinds of single-crystal (100) 8-mol% Y2O3 doped zirconia (YSZ) were used as substrate: with one surface polished and with

A new family of the Pb-based layered cuprate with the 1222 structure has been synthesized in the (Pb,S)Sr2(RE,Ce)2Cu2O z (RE=Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, and Y) system. The almost-single phase samples are obtained for x=0.25 and y=1.0 in the c

We have synthesized new Pb-based 1222 cuprates containing sulfur in the (Pb0.75S0.25)Sr2(Eu2.0−x Ce x )Cu2O z system. X-ray diffraction study shows that almost the single 1222 phase samples can be obtained for a considerable wide area of 0.3≤x≤

New Pb-based 1222 cuprates containing phosphorus have been synthesized in the (Pb0.75P0.25)Sr2- (RE2–x–yCexSry)Cu2Oz (RE = Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, and Y) systems. The almost-single phase samples are obtained for 0.5≤x≤1.0 and y=0.

We previously reported on the synthesis of new Pb-based 1222 superconductor containing phosphorus in the (Pb0.75P0.25)Sr2(Eu1.9−xCexSr0.1)Cu2Oz system. Recently, we have discovered new members of the Pb-based 1222 superconductor containing phosphor

We already reported on the synthesis of new Pb-based 1212 layered cuprates containing sulfur in the (Pb0.75S0.25)Sr2(Y,Ca)Cu2Oz system. There none of the samples showed superconductivity until after annealing under high O2 pressure. More recently, we

The Pb-based 1212 compounds containing phosphorus were already discovered by us in the (Pb,P)Sr2(Y,Ca)Cu2Oz system. Among the almost-single phase samples, a sample with the nominal composition of (Pb0.75P0.25)Sr2(Y0.4Ca0.6)Cu2Oz was a superconductor

New Pb-based 1212 layered cuprates containing sulfur have been synthesized in the (Pb0.75S0.25) Sr2 (Y1−xCax) Cu2Oz system. X-ray diffraction analysis shows that the almost single-phase samples are obtained within a region of 0.0≤x≤0.5. The cry
