4D-STEM data on fast- and slow-quenched sputtered metallic glass films associated with "Spatial distribution and connectivity of medium-range order signatures in a metallic glass probed with simulated and experimental 4DSTEM" (scientific article published in Journal of Alloys and Compounds, 2026)

This dataset consists of 4-dimensional scanning transmission electron microscopy diffraction data collected on a NION Hermes at 200 keV for two different sputtered films of Pd77.5Cu6.0Si16.5. These two different samples represent two different states, referred to as "more-relaxed"/"slow-quenched" and "less-relaxed"/"fast-quenched" in the paper specified under "related work". This manuscript also contains experimental details.

npy files contain the measured data, which consists of 100x100 sites on the sample, equally spaced in two dimensions. At each site, a diffraction pattern of 250 x 250 pixels was recorded.

json files contain the meta data to the respective data set.

Files 1) to 4) correspond to the "more-relaxed"/"slow-quenched" sample. Files 1) and 2) where measured (at two different sites) at location A, files 3) and 4) (at two different sites) at location B, where the distance between locations A and B is much larger than the length scale covered in the contained maps.

Files 5) to 8) correspond to the "less-relaxed"/"fast-quenched" sample. Files 5) and 6) where measured (at two different sites) at location C, files 7) and 8) (at two different sites) at location D, where the distance between locations C and D is much larger than the length scale covered in the contained maps.
