PROJECT TITLE :
Low-Temperature Scaling of the Critical Current in 1 G HTS Wires
We gift highly detailed temperature, magnetic field and field angle dependent measurements of the essential current of a state-of-the-art commercial first-generation Bi-2223 hot temperature superconductor wire (Sumitomo new kind H high current density DI-BSCCO). By scaling the applied field values at totally different angles using the Blatter electron mass anisotropy expression, we demonstrate that the measurements at every temperature from twenty to eighty five K collapse onto a typical curve with respect to the scaled magnetic field. But, the scaling parameter is found to vary from seven at 80 K to thirteen at 25 K, way below the values reported in the literature for the electron mass anisotropy of this material, and so much nearer to the values reported for similar analyses of data obtained from the much less anisotropic superconductor YBCO. This suggests that a mechanism of similar magnitude underlies and determines the results obtained for each materials no matter their greatly differing electronic mass anisotropies. By normalizing the results to the self-field vital current and therefore the irreversibility field, we tend to are able to obtain a single universal curve describing the performance of the superconductor across the total vary of operating conditions. In distinction to pinning-engineered YBCO coated conductors, we have a tendency to find that the low-temperature behavior of BSCCO wires can be well correlated with its high-temperature behavior. Data of this straightforward behavior of this commercial superconductor across the complete parameter space of temperature, field and field angle will be invaluable to engineers working with this material to construct machines or devices.
