Two-step phase transitions in Fe(Se,Te)
D. A. Chareev, A. A. Gippius, Y. A. Ovchenkov +6
In the studied crystals of FeSe0.7 Te0.3 , a structural phase transition occurs in two stages. At higher temperatures, the electronic subsystem undergoes a reconstruction, leading…
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…
Crossover from nematic to magnetic low-temperature ground state in Fe(Se,Te) compounds
Y. A. Ovchenkov, D. A. Chareev, D. E. Presnov +2
A comparative analysis of the properties of FeSeTe crystals in the range of x values of about 0.4 and pure FeSe crystals is presented. We found that the anomaly i…
Phase separation near the charge neutrality point in FeSeTe crystals with x 0.15
Y. A. Ovchenkov, D. A. Chareev, E. S. Kozlyakova +6
Our study of FeSeTe crystals with x 0.15 shows that the phase separation in these compositions occurs into phases with a different stoichiometry of iron. This…
Short-lived electron excitations in as revealed by microwave absorption
I. I. Gimazov, N. M. Lyadov, D. A. Chareev +2
The \ single crystals with the various Se/Te ratios were studied by the microwave absorption and direct current resistivity measurements. The comparison o…
Crystal structure and phase transitions at high pressures in the superconductor FeSe0.89S0.11
Yulia A. Nikiforova, Anna G. Ivanova, Kirill V. Frolov +8
We report on the structural phase transitions in the S doped FeSe superconductor by powder synchrotron X ray diffraction at high pressures up to 18.5 GPa under compression and deco…
