Distinct 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 کاملHigh critical-current superconductor-InAs nanowire-superconductor junctions.
We report on the fabrication of InAs nanowires coupled to superconducting leads with high critical current and widely tunable conductance. We implemented a double lift-off nanofabrication method to get very short nanowire devices with Ohmic contacts. We observe very high critical currents of up to 800 nA in a wire with a diameter of 80 nm. The current-voltage characteristics of longer and suspe...
متن کاملEnhanced critical current density in the pressure-induced magnetic state of the high-temperature superconductor FeSe
We investigate the relation of the critical current density (Jc) and the remarkably increased superconducting transition temperature (Tc) for the FeSe single crystals under pressures up to 2.43 GPa, where the Tc is increased by ~8 K/GPa. The critical current density corresponding to the free flux flow is monotonically enhanced by pressure which is due to the increase in Tc, whereas the depinnin...
متن کاملMagnetic Field Dependence of the Transport Critical Current Density in the Superconductor Family ReBa2Cu3O7-x
The magnetic field dependence of the transport critical current density has been investigated at temperatures of 78K and 68K in bulk polycrystalline samples of the hightemperature superconductor ReBa2Cu3O7-x, where Re (rare earth) = Y (yttrium), Er (erbium), Yb (ytterbium), Ho (holmium), and Dy (dysprosium). Samples were sintered in 1⁄4 inch pellet form after the conventional ceramic processing...
متن کاملEnhancement of the critical current density and flux pinning of MgB2 superconductor by nanoparticle SiC doping
Doping of MgB2 by nano-SiC and its potential for the improvement of flux pinning were studied for MgB22x(SiC)x/2 with x50, 0.2, and 0.3 and for 10 wt % nano-SiC-doped MgB2 samples. Cosubstitution of B by Si and C counterbalanced the effects of single-element doping, decreasing Tc by only 1.5 K, introducing intragrain pinning centers effective at high fields and temperatures, and significantly e...
