The Superconducting Properties for La–Sr–Cu–O Systems

Superconducting oxides, La–Sr–Cu–O and Y–Ba–Cu–O were prepared using nitrate mixture by spray dry method and/or oxide and carbonate powder mixtures followed by pressing and sintering. The superconducting properties such as critical temperature (T c ) and critical current density (J c ) were measured...

Summary:Superconducting oxides, La–Sr–Cu–O and Y–Ba–Cu–O were prepared using nitrate mixture by spray dry method and/or oxide and carbonate powder mixtures followed by pressing and sintering. The superconducting properties such as critical temperature (T c ) and critical current density (J c ) were measured by resistive and inductive methods, and transport current and magnetization measurements, respectively. The T c 's(the resistive offset) were 32, 91 K for La and Y system, respectively. The J c (77K) of 1,840 A/cm 2 was observed for Y system by transport current measurement.
