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.
