this invention enables high temperature superconducting metal oxide materials reba 2 cu 3 o x bco ) to carry high superconducting currents at high current densities under high magnetic field , in all orientations of the field , and at high temperatures . the superconductor is adapted to carry current in a superconducting state , with the superconductor having a current carrying capacity of at least 250 a / cm width , in a field of 3 tesla , at 65 kelvin , at all angles relative to the coated conductor . more preferably , the current carrying capacity extends through the range of substantially 250 a / cm to 500 a / cm . excellent performance is achieved by use of intrinsic pinning centers in the hts compound . the invention preferably does not require the addition of extra elements or compounds or particles to the superconducting compound during synthesis , nor does it require extra process steps .
