The field dependence of the resistivity and the critical current density, Jc(B), ofMgB2 doped with10wt%

wet and dry succinic acid have been investigated by magnetic measurements.The dry succinic acid

significantly ...

MgB2 superconductor samples co-doped with 0.02 wt. Al2O3 and 0-0.05 wt. SiC were studied by magnetization – magnetic field (M-H) loop measurements at different temperatures. The critical current density has been calculated ...

We present the following results: 1) We introduce a doping source for MgB2, liquid SiCl4, which is free of C, to significantly enhance the irreversibility field (Hirr) , the upper critical field (Hc2), and the critical current ...
