Dataset for "Imaging of strong vortex pinning in GdBaCuO high temperature superconducting tapes under external fields"
This dataset contains data from the research into the vortex pinning in GdBaCuO superconducting tapes under external fields. The bulk of the data is Scanning Hall Probe Microscopy (SHPM) image files. The remainder of the data includes; electronic transport data, EDX and SEM data files and files for B-H loops.

Documentation
Data collection method:
The data was acquired by scanning Hall microscopy (SHM) in the rapid 'flying' mode that makes a rapid 2D magnetic scan of the maximum field of view. The data files consist of individual SHM images collected during these scans along with the appropriate text files for their averages. B-H loops were measured via the SHPM in fields up to 107mT and 3.2mT. Transport data was performed in an Oxford Instruments Cryostat cooled by liquid Nitrogen. A current of 10mA was supplied while the voltage was measured using a Keithley 182 nanovoltmeter as the temperature was swept at 0.1K/min using an OI ITC 503 temperature controller. Field Effect Scanning Electron Microscopy (FE-SEM) at 5kV and 1kV and Energy Dispersive X-Ray Analysis (EDX) at 10kV were performed in a Joel JSM-6301F FE-SEM.
Data processing and preparation activities:
The SHM image data in the archive are raw as-captured data without any post-processing.
Technical details and requirements:
SHM image datasets are formatted as the magnetic induction in Gauss measured at each point on a 1 128× 128 array of pixel positions. Temperature was varied between 10K and 88K. The scan area changes between temperatures with the following fitting: Area=(-1.037e-08*Temperature^4 + 5.547e-06*Temperature^3 + -0.0009229*Temperature^2 + 0.2264*Temperature + 6.483) EDX data must be viewed via Oxford Instruments analysis suite.
