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…
Effect of Mn Substitution on Superconductivity in PrFeAs(O,F): Role of Magnetic Impurities
Priya Singh, Konrad Kwatek, Tatiana Zajarniuk +5
We investigate Mn substitution at the Fe site in PrFe1-xMnxAsO0.7F0.3 (0 to 0.1) using structural, Raman, density functional theory (DFT), transport, and magnetic measurements. X-r…
Complete electronic phase diagram and enhanced superconductivity in fluorine-doped PrFeAsO1-xFx
Priya Singh, Konrad Kwatek, Tatiana Zajarniuk +4
Establishing a complete electronic phase diagram for REFeAsO (RE = rare earth, RE1111) ironbased superconductors has remained experimentally challenging. Here, we report a systemat…
Effect of spark plasma sintering on the superconducting properties of Sm-based oxypnictide
Mohammad Azam, Tatiana Zajarniuk, Konrad Kwatek +2
We optimize the superconducting properties of Sm-based oxypnictide (Sm1111: SmFeAsO0.80F0.20) by using the Spark Plasma Sintering (SPS) technique under various synthesis conditions…
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…
Impact of LiBSO glass additive on the structure and electrical properties of the LATP-based ceramics
K. Kwatek, W. Ślubowska, J. Trébosc +2
The existing solid electrolytes for lithium ion batteries suffer from low total ionic conductivity, which restricts its usefulness for the lithium-ion battery technology. Among the…
