Samples of YBazCudOs are prepared by means of a new high oxygen pressure technique employing oxygen-HIP. Both magnetization and resistivity measurements show the superconductivity transition at 82.5 K. The lower and upper critical fields of YBa&\_t40s are obtained from the magnetization measurements
Raman spectra of Yl-xCaxBa2Cu408 were investigated. At the Ca concentraiton of 10 %, which was solubility limit, frequency shift of 2 cm -1 was observed in the peaks at 492 cm -1 and 595 cm "1 assigned to the motion of 0(1) and 0(4) atoms, respectively. It is suggested that the stractural change due
Pr substituted YBa2Cu4Os ( 1 : 2: 4) has been synthesized by a solid-state reaction at 930 ยฐ C-950 ยฐ C in 200 bar oxygen pressure. Pr could be substituted only up to 20% i.e., Yo.sPro.2Ba2Cu4Os. Tc decreased with increasing Pr; however, Tc could be restored by co-substitution of Ca along with Pr whi
