Dataset for "Observing the suppression of superconductivity in RbEuFe4As4 by correlated magnetic fluctuations"
These are files which include (a) magnetic images taken by our Scanning Hall Probe Microscope magnetic imager of the superconducting crystal, RbEuFeAs; (b) the electrical and magnetization data of the crystal performed by American collaborators at Argonne National Laboratory.
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.
Transport data, performed at Bath, and magnetization data, performed at Argonne National Laboratory, for figure 1 are also included.

Data collection method:
Magnetic images were obtained by scanning Hall probe microscopy. This involves rastering a GaAs Hall probe located in close proximity to a scanning tunnelling microscope tip over the sample of interest via a piezoelectric tube. At each step the Hall voltage is recorded and converted into a magnetic field via a known Hall co-efficient, thus producing the magnetic map. Electronic transport measurements were performed by attaching gold wires with silver epoxy in a standard 5-lead Hall bar configuration. The in-plane resistivity was then measured as a function of temperature in a Quantum Design MPMS-7 system at Argonne National Labs.
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. At the measurement temperatures of 35K, 30K, 25K, 20K, 17.5K, 16.25K, 15K, 13.75K, 12.5K, 10K, 7.5K and 5K. 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)
