dc.description.abstractAmong the recently discovered Fe-based superconducting compounds, the Ba-122 phase has proved to be the more attracting for the development of powder in tube (PIT) processed conductors. In fact, after some years of development, critical current densities (<italic>J<sub>c</sub></italic>) of about 10<sup>5</sup> A/cm<sup>2</sup> at 4.2 K and magnetic fields up to 10 T have been obtained in (Ba<sub>0.6</sub>K<sub>0.4</sub>)Fe<sub>2</sub>As<sub> 2</sub>, PIT wires and tapes. To develop a safe upscaling method, the synthesis of the powders is a crucial point. In order to avoid the use of highly reactive K we have developed BaFe<sub>2</sub>(P<sub>1-x</sub>As<sub>x</sub>)<sub>2 </sub> PIT tapes. This compound has proved to be very stable and in form of crystals and thin films exhibits excellent critical current: We succeeded in manufacturing PIT tapes with this phase with <italic>J<sub>c</sub></italic> values of about 10<sup>3</sup> A/cm<sup>2</sup> at 4.2 K in self-field. Detailed microstructural and chemical investigations of the samples have been performed by high-resolution TEM, scanning TEM, and electron energy loss spectrometry analysis. A deformation network inside the grains that can induce strong pinning has been observed. However, chemical inhomogeneities at the grain boundaries are also present, which limit the transport current.
