Superconductivity (SC) with the suppression of long-range antiferromagnetic (AFM) order is observed in the parent compounds of both iron-based and cuprate superconductors. The AFM wave vectors are bicollinear (π, 0) in the parent compound FeTe different from the collinear AFM order (π, π) in most iron pnictides. Study of the phase diagram of Fe1+yTe1−xSex is the most direct way to investigate the competition between bicollinear AFM and SC. However, presence of interstitial Fe affects both… 

Review of annealing effects and superconductivity in Fe1+yTe1−xSex superconductors

Among iron-based superconductors, Fe1+yTe1−xSex is unique in its structural simplicity, consisting of only FeTe/Se layers, which is favorable for probing the mechanism of superconductivity. Recently,

Electronic phase diagram of iron chalcogenide superconductors FeSe1-xSx and FeSe1-yTey

Here we establish a combined electronic phase diagram of isoelectronic FeSe1-xSx (0.19 > x > 0.0) and FeSe1-yTey (0.04 < y < 1.0) single crystals. The FeSe1-yTey crystals with y = 0.04 - 0.30 are

Electronic transport properties and hydrostatic pressure effect of FeSe0.67Te0.33 single crystals free of phase separation

Thermal evolution of resistivity, ρ(T, x), of as-prepared samples of Fe1+δTe1−xSx (δ ≈ 0, x ≤ 0.2 = solubility limit) demonstrate a granular log-in-T character within Ts < T <300K, a Kondo-like

Correlation-driven electronic reconstruction in FeTe1−xSex

Electronic correlation is of fundamental importance to high temperature superconductivity. While the low energy electronic states in cuprates are dominantly affected by correlation effects across the

Tuning across the BCS-BEC crossover in the multiband superconductor Fe1+ySexTe1−x: An angle-resolved photoemission study

This work realizes the BCS-BEC crossover in a nearly compensated semimetal, Fe1+ySexTe1−x, by tuning the Fermi energy εF via chemical doping, which permits us to systematically change Δ/εF from 0.16 to 0.50.

Electronic phase diagram of Fe1+yTe1−xSex revealed by magnetotransport measurements

Among the Fe-based superconductors, Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ is unique in that its crystal structure is the simplest and the electron correlation level is the strongest, and thus it is important

Thermal post processing of FeSe1−xTex: formation of surface iron oxides and enhancement of Jc

Superconductivity in the PbO-type structure α-FeSe

The observation of superconductivity with zero-resistance transition temperature at 8 K in the PbO-type α-FeSe compound is reported, indicating that this compound has the same, perhaps simpler, planar crystal sublattice as the layered oxypnictides.

Electronic and magnetic phase diagram of beta-Fe(1.01)Se with superconductivity at 36.7 K under pressure.

The magnetic and electronic phase diagram of beta-Fe(1.01)Se is reported, which shows a marked change in volume at the same time as T(C) rises, owing to a collapse of the separation between the Fe(2)Se(2), and it is reported that at higher pressures, Fe(1)Se transforms to a hexagonal NiAs-type structure and exhibits non-magnetic behaviour.
