Description

This dataset contains experimental data related to the high-pressure synthesis and characterization of PrFeAsO1-xFx iron-based superconducting materials. It provides structural, transport, and magnetic characterization of PrFeAsO1-xFx compounds synthesized under high-pressure conditions, with a focus on the effects of high-pressure synthesis on phase formation and superconducting properties.

The dataset includes experimental and characterization results obtained during the preparation and investigation of the synthesized samples. These data support the analysis and conclusions presented in the associated Physica C publication and provide information on the structural/phase characteristics and superconducting behavior of the investigated materials.

All data are provided in text-based formats suitable for independent analysis, and reuse. The dataset is intended to facilitate further research and comparison in studies of high-pressure synthesis, phase formation, and superconductivity in iron-based superconductors.

The dataset is associated with the publication “Effects of high-pressure synthesis on phase formation and superconducting properties of PrFeAsO1-xFx” published in Physica C.

Contains powder X-ray diffraction (XRD) data for PrFeAsO1-xFx samples with nominal fluorine concentrations x = 0.2, 0.3, and 0.5, synthesized by conventional synthesis at ambient pressure (CSP-AP) and high-pressure high-temperature synthesis (HP-HTS). The text files contain diffraction intensity (a.u.) as a function of diffraction angle, 2θ (degrees). The archive also includes the Rietveld refinement data for the x = 0.2_HIP sample, containing the experimental, calculated, and difference profiles as a function of 2θ. These data are used to investigate phase formation and structural changes associated with HP-HTS processing.

Contains structural parameter data for PrFeAsO1-xFx samples synthesized by conventional synthesis at ambient pressure (CSP-AP) and high-pressure high-temperature synthesis (HP-HTS). The text files provide the lattice parameters a (Å) and c (Å), and unit-cell volume V (ų) as a function of the nominal fluorine concentration x = 0.2, 0.3, and 0.5. The data are used to compare the structural evolution of the samples before and after HP-HTS processing.

Contains electrical resistivity data for PrFeAsO1-xFx samples with nominal x = 0.2, including the conventionally synthesized sample (x = 0.2) and the high-pressure high-temperature synthesized sample (0.2_HIP). The text files provide normalized electrical resistivity, ρ/ρ₆₀K, as a function of temperature. Files labeled “InsetFigure” contain the extended temperature range up to 300 K, corresponding to the inset shown in Figure 4.
