Anisotropy of the critical current in MgB2 tapes made of high energy milled precursor powder
For applications of MgB2 wires or tapes, high critical currents in high magnetic fields are essential. By using tapes in superconducting coils the anisotropic behaviour of the critical current, i.e. the dependence on the direction of the external field in relation to the tape surface, has to be taken into account. The anisotropy of MgB2 tapes with mechanically alloyed (MA) precursor powder and ...
متن کاملStrongly enhanced current densities in Sr0.6K0.4Fe2As2 + Sn superconducting tapes
Improving transport current has been the primary topic for practical application of superconducting wires and tapes. However, the porous nature of powder-in-tube (PIT) processed iron-based tapes is one of the important reasons for low critical current density (Jc) values. In this work, the superconducting core density of ex-situ Sr0.6K0.4Fe2As2 + Sn tapes, prepared from optimized precursors, wa...
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...

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 کاملAchievement of practical level critical current densities in Ba1−xKxFe2As2/Ag tapes by conventional cold mechanical deformation
The recently discovered iron-based superconductors are potential candidates for high-field magnet applications. However, the critical current densities (J(c)) of iron-based superconducting wires remain far below the level needed for practical applications. Here, we show that the transport Jc of Ba₁-xKxFe₂As₂/Ag tapes is significantly enhanced by the combination process of cold flat rolling and ...
