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.
