Description
This dataset contains the raw data for the journal article “Understanding the porosity and its effects on the superconducting properties of YBCO single grains”.
The file “README.txt” contains detailed information about the measurement of the raw data and the determination of the data shown in the paper.
The .tif files contain tracking microscope images (OLYMPUS BX51M) of all 22 investigated YBCO bulk superconductors (5x 13.6 mm, 5x 16.0 mm, 5x 20.8 mm, 4x 24.8 mm, 2x 30.7 mm, and 1x 41.8 mm diameter).
The file “Raw_data.xlsx” contains the sample number, diameter, height, area, pore count, average pore size and porosity of each of the 22 samples investigated. Furthermore, the file contains the maximum/minimum trapped field measured at the top and bottom of each sample. The average critical current density at the top/bottom of each sample was calculated with the formula shown in Equation 4 in the paper. Furthermore, “Raw_data.xlsx” contains the pore sizes measured for each sample set (Figure 6 in publication).
The file “Raw_data_trapped_field.xlsx” contains the raw data for the trapped field profiles measured with 18 rotating hall probes 1.5 mm above the sample surface at 77 K (Figure 3 in publication).
