Pressure-Tuned Competing Electronic States in Layered Tellurides
Mahmoud Abdel-Hafiez, Govindaraj Lingannan, D. A. Chareev +7
Layered transition-metal dichalcogenides (TMDs) host competing electronic states that can be tuned by external perturbations, providing a platform to explore the interplay between…
Competition between orbital effects, Pauli limiting, and Fulde-Ferrell-Larkin-Ovchinnikov states in 2D transition metal dichalcogenide superconductors
Chang-woo Cho, Cheuk Yin Ng, Mahmoud Abdel-Hafiez +4
We compare the upper critical field of bulk single-crystalline samples of the two intrinsic transition metal dichalcogenide (TMD) superconductors, 2H-NbSe2 and 2H-NbS2, in high mag…
Intra-Atomic and Local Exchange Fields in the Van der Waals Magnet CrI3
Anirudha Ghosh, H. Johan M. Jonsson, D. J. Mukkattukavil +14
We report on a combined experimental and theoretical study on CrI3 single crystals by employing the polarization dependence of resonant inelastic X-ray scattering (RIXS). Our inves…
Coexistence of Superconductivity and Charge Density Wave in Tantalum Disulfide: Experiment and Theory
Y. Kvashnin, D. VanGennep, M. Mito +6
The coexistence of charge density wave (CDW) and superconductivity in tantalum disulfide (2H-TaS) at ambient pressure, is boosted by applying hydrostatic pressures up to 30GPa,…
Pressure-Induced Re-entrant transition in NbS3 Phases: Combined Raman Scattering and X-ray Diffraction Study
Abdel-Hafiez, M. Thiyagarajan, R. Majumdar +13
We report the evolution of charge density wave states under pressure for two NbS3 phases triclinic (phase I) and monoclinic (phase II) at room temperature. Raman and X-ray diffract…
High-Pressure Phase Diagram of NdFeAsOF: Disappearance of superconductivity on the verge of ferromagnetism from nd moments
Mahmoud Abdel-Hafiez, M. Mito, K. Shibayama +5
We investigated transport and magnetic properties of NdFeAsOF single crystal under hydrostatic pressures up to 50\,GPa. The ambient pressure superconductivity at $T…
Anomalous correlation effects and unique phase diagram of electron doped FeSe revealed by angle resolved photoemission spectroscopy
C. H. P. Wen, H. C. Xu, C. Chen +9
In FeSe-derived superconductors, the lack of a systematic and clean control on the carrier concentration prevents the comprehensive understanding on the phase diagram and the inter…
Superconducting properties of sulfur-doped iron selenide
Mahmoud Abdel-Hafiez, Yuan-Yuan Zhang, Zi-Yu Cao +8
The recent discovery of high-temperature superconductivity in single-layer iron selenide has generated significant experimental interest for optimizing the superconducting properti…
Temperature dependence of lower critical field Hc1(T) shows nodeless superconductivity in FeSe
M. Abdel-Hafiez, J. Ge, A. N. Vasiliev +4
We investigate the temperature dependence of the lower critical field Hc1(T) of a high-quality FeSe single crystal under static magnetic fields H parallel to the c axis. The temper…
Lower critical field and SNS-Andreev spectroscopy of 122-arsenides: Evidence of nodeless superconducting gap
M. Abdel-Hafiez, P. J. Pereira, S. A. Kuzmichev +10
Using two experimental techniques, we studied single crystals of the 122-FeAs family with almost the same critical temperature, Tc. We investigated the temperature dependence of th…
