We report tunneling measurements of the superconducting energy gaps in YBa.Cu307 and Bi2Sr.CaCthO 8 using b~eak junctions. The differential conductance d/fdV at T = 4.2 K shows no leakage around zero ba~s, while the t,,q~ -dge peaks m d//dV are somewhat broadened compared to the simple BCS density o
We have presented the results of Zn and Ga substitution in place of Cu in YBa,&Os (Y-124). The samples of YBaZ(Cu,\_,Zn,)40s with x=0.00-0.20 and YBaZ(Cu,\_,GaX)dOs with x=0.01-0.10 were synthesised at ambient oxygen pressure using sodium oxalate. With increase in concentration of Zn in Y-124 no sig
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
