CRITICAL CURRENT DENSITIES OF SUPERCONDUCTING YBA2CU4O8 SYNTHESIZED BY THE CITRATE GEL PROCESS
High-Tc superconducting YBa2Cu4O8 submicron powders with transition temperature around 80 K were successfully synthesized via citrate gel process at one atmosphere oxygen pressure. An intragrain critical current density of up to 1.3×107A/cm2 at 6 K and H=1 T has been measured by magnetisation method...
