Studies on the title compounds show that while La and Pr form complete solid solutions, Tb does not substitute for Y. Superconducting transition temperature (Tc) decreased with increasing x from 91K but pronounced effect is noted for Ln=Pr. PrBa2Cu3O7 exhibits a semiconductor behavior. © 1988 Elsevier Science Publishers B.V.

Superconductivity studies on (Y1-xLnx)Ba2Cu3O7, Ln=La,Pr,Tb

Physica C: Superconductivity and its applications

Critical current density measurements were performed on compounds of the type (PrxY1-x)Ba2Cu3O7-y as a function of temperature, applied magnetic field and composition. The analysis yielded results which are qualitatively similar to those observed in the case of YBa2(Cu1-xFex)3O2 and TI-2122 as well as 2223 compounds. © 1991.

Cryogenics

Intragrain critical current density of superconducting compounds of the type (PrxY1-x)Ba2Cu3O7-y

Magnetization was measured on Pr-doped YBa2Cu3O7−y for fields up to 5·5T. The paramagnetic behaviour is correlated to the free ion values of Pr3+ and Pr4+. Hysteresis experiments were done for superconducting composition for fields up to 1100 Gauss. The intragrain critical current density is calculated using Bena’s formula. © 1991, Indian Academy of Sciences. All rights reserved.
