Critical current densities in superconducting materials
We discuss recent research in the area of critical current densities (JC) in superconductors. This shall cover recent work on newly discovered superconductors, as well as on the magnetic-field dependence of JC .
متن کاملTransport and magnetic critical current in superconducting MgB2 wires
Direct comparison of the magnetic and transport critical current density (Jc) for the same pieces of copper-sheathed MgB2 wires shows a large discrepancy in magnitude and field dependence of the two. The value of magnetic Jc can differ from the value of transport Jc by a factor of 10 or more. This discrepancy does not occur merely because of the difference in the voltage at which the magnetic a...
متن کاملMagnetically modulated critical current densities of Co/Nb hybrid
By tuning morphology and size of magnetic subsystem, ferromagnet-superconductor (F/S) hybrid system provides an effective way to modulate superconductivity due to the interaction between superconducting and magnetic-order parameters at the mesoscopic length scale. In this work, we report on investigations of critical current density in a large-area Co/Nb hybrid via facile colloidal lithography....
متن کاملFabrication of Chemically Doped, High Upper Critical Field Magnesium Diboride Superconducting Wires
Controlled chemical doping of magnesium diboride (MgB2) has been shown to substantially improve its superconducting properties to the levels required for high field magnets, but the doping is difficult to accomplish through the usual route of solid state reaction and diffusion. Further, superconducting cables of MgB2 are difficult to fabricate because of the friable nature of the material. In t...
