Abstract: A coated conductor comprises a substrate supporting a ReBCO superconductor adapted to carry current in a superconducting state. The superconductor is characterized in having peaks in critical current (Jc) of at least 0.2 MA/cm2 in a magnetic field of about 1 Tesla when the field is applied normal to the surface of the superconductor and when the field is applied parallel to the surface of the superconductor, and further characterized in that the superconductor includes horizontal defects and columnar detects in a size and an amount sufficient to result in the said critical current response. The conductor is characterized in that the ratio of the height of the peaks in the Jc is in the range from 3:1 with the ratio of the field perpendicular (0 degrees) to the field parallel (+/−90 degrees) to the range from 3:1 with the ratio of the field parallel to the field perpendicular.
