Effects of high-pressure synthesis on phase formation and superconducting properties of PrFeAsO1-xFx
Priya Singh, Konrad Kwatek, Tatiana Zajarniuk +3
Motivated by recent reports of enhanced superconducting performance in several families of iron-based superconductors (IBS) processed by high-pressure (HP) synthesis, we investigat…
Tuning Superconductivity by Isovalent Antimony Substitution in PrFeAs(O,F)
Priya Singh, Konrad Kwatek, Tatiana Zajarniuk +6
We investigate the effects of isovalent Sb substitution at the As site in fluorine-doped PrFeAs1-xSbxO0.7F0.3 (x = 0 to 1.0) through structural, Raman spectroscopy, density functio…

A series of Mn-doped CaKFe4As4 samples, CaK(Fe1-xMnx)4As4 with x values of 0, 0.005, 0.01, 0.02, 0.03, 0.04, and 0.05, are synthesized using two distinct routes: conventional synth…
Praseodymium doping effect on the superconducting properties of FeSeTe bulks under ambient and high-pressure growth conditions
Priya Singh, Manasa Manasa, Mohammad Azam +9
A series of Pr-doped FeSeTe (FePrSeTe; to 0.3) bulks are prepared by conventional synthesis process at ambient pressure (CSP), a…
Synthesis and characterizations of arsenic doped FeSe bulks
Priya Singh, Manasa Manasa, Mohammad Azam +6
FeSe(11) family has a simple crystal structure belonging to iron-based superconductors (FBS) and has many stable phases including hexagonal and tetragonal structures, but only the…
High-pressure growth effects on the superconducting properties of Sm-based oxypnictide superconductors
Mohammad Azam, Manasa Manasa, Tatiana Zajarniuk +8
High-pressure synthesis can be an effective method for improving the sample quality of materials as well as their superconducting properties. In this paper, the synthesis process o…
