We have investigated the magnetic susceptibility at atmospheric pressure for the (Y1-xPrx)2Ba4Cu7015.6 system with x=0.1-0.6 and that at high pressure for the sample with x=0.6. The effective moment per Pr ion obtained by the Curie-Weiss fitting is an intermediate value between that expected for Pr
The concentration dependence of the transition temperature T c has been studied in the high-T c compounds (Y~ xTlx)-Ba2Cu307 y, Y(Ba 1 xKx)2Cu307 y and YBa2(Cu I xMg~)307 y. In the TI-compound, the results show little effect on T C. In the K-compound, T~ gradually drops with increasing K concentrati
