Datasets underpinning five of the six Figures and four Supplementary Figures in "Breakdown of the critical state in the ferromagnetic superconductor EuFe2(As1-xPx)2" in Superconductor Science and Technology. The primary data (e.g. as in Figure 2) are low temperature Hall magnetometry measurements made at the University of Bath. The manuscript describes in detail how these measurements are made. There is further, secondary data (e.g. penetration field Hp) that are derived from analysis of these primary measurements. 2025-12-23 University of Bath public RightsHolder University of Bath Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/X015033/1 Intrinsic Pinning in Magnetic Iron-Based Superconductors; a Route to High Critical Current Conductors at High Magnetic Fields cent_nan The dataset contains Hall sensor magnetometry data from measurements made on single crystals of the ferromagnetic iron-based superconductor EuFe2(As1-xPx)2. The first sample (#1) has Tc~24 K, x~0.21. The second sample (#2) has Tc~12 K, x~0.28. The magnetometry measurements were performed at the University of Bath using a home-built system. The measurements are made at temperatures ranging from ~30 K to ~5 K, and in magnetic fields up to +/- 17 mT. Further data were derived from analysis of the primary measurements, such as the penetration field (Hp) or the analysis of characteristic fluctuations in the measurements. All data are in the form of .csv (comma separated values) with headers and units indicated. No specialist software is required to view the data. en 1 10.15125/BATH-01597 https://doi.org/10.1088/1361-6668/ae2b3a pub David Bullett Nanofabrication Facility 91ea5584-75f9-4093-ad28-b038c72e906b open
