Dataset for "Magnetically-controlled Vortex Dynamics in a Ferromagnetic Superconductor"
Datasets underpinning the five Figures and six Supplementary Figures for "Magnetically-controlled Vortex Dynamics in a Ferromagnetic Superconductor" in Communications Materials.
The primary data are a mixture of low temperature magnetisation data, taken using a SQUID magnetometer taken at the University of Bristol, and low temperature magnetic force microscopy (MFM) scan data taken at the University of Basel. Additionally, there are data derived from analysis of the magnetisation data, e.g. critical current, coercive field, as well as the results of magnetic relaxation measurements, i.e. Ueff. In addition to the MFM scan data are line profiles taken through regions of these scans.
The supplementary data include further magnetisation data, as well as examples of magnetic relaxation data. Additionally, there is a further example of a line profile taken from MFM scan data, along with corresponding fitted data.

Data collection method:
The dataset contains magnetisation and magnetic force microscopy data, with measurements performed on single crystals of the ferromagnetic iron-based superconductor EuFe2(As1-xPx)2, with x~0.21, Tc~24 K and T_FM~19 K. Magnetisation data was collected using a Quantum Design SQUID magnetometer at the University of Bristol, at temperatures ranging from 5.0 to 25.0 K and magnetic fields ranging in magnitude up to 10,000 Oe (1 Tesla). The measurements were primarily in the form of magnetic hysteresis loops, with some further measurements of magnetic relaxation. From this data, quantities such as magnetic susceptibility, coercive field, critical current density and effective pinning potential are derived. Magnetic force microscopy (MFM) data were acquired using a home-built oscillating magnetic nanowire microscope at the University of Basel. Scan data were acquired in temperatures ranging from approximately 22 K down to 4.3 K, and in magnetic fields ranging in magnitude up to 10,000 Oe (1 Tesla). Line profiles were derived from these 2D scan data.
