Interlaboratory Comparison on High-Temperature Superconductor Critical-Current Measurements
An extensive interlaboratory comparison was conducted on high temperature superconductor (HTS) critical-current measurements. This study was part of an international cooperative effort through the Versailles Project on Advanced Materials and Standards (VAMAS). The study involved six U.S. laboratories that are recognized leaders in the field of HTS. This paper includes the complete results from ...
متن کاملDistinct doping dependence of critical temperature and critical current density in Ba1−xKxFe2As2 superconductor
Since the high transition temperature (High-Tc) superconductivity was discovered in the series of materials containing iron (Fe), their potential for the applications has been extensively scrutinized. In particular, a lot of effort has been made in achieving the high current-carrying ability by revealing the vortex pinning behavior. Here, we report on the critical current density (Jc) for the p...
متن کاملResistivity vs. Temperature of a Superconductor
• Calibrate a transducer (silicon diode) for low-temperature measurements and measure temperatures down to that of boiling liquid nitrogen. • Accurately measure very low voltages, including techniques for reducing or compensating for electronic noise. • Identify the source of and compensate for systematic error(s) in measurements. • Examine the behavior of a high-Tc superconductor sample during...
متن کاملCritical voltage of a mesoscopic superconductor.
We study the influence of a voltage-driven nonequilibrium of quasiparticles on the properties of short mesoscopic superconducting wires. We employ a numerical calculation based upon the Usadel equation. Going beyond linear response, we find a nonthermal energy distribution of the quasiparticles caused by the applied bias voltage. It is demonstrated that this nonequilibrium drives the system fro...
