Title: Role of chalcogen vapor annealing in inducing bulk superconductivity in Fe_1+yTe_1-xSe_x [How does annealing in chalcogen vapor induce superconductivity in Fe_1+yTe_-xSe_x?]

Abstract

Recent investigations have shown that Fe_1+yTe_1-xSe_x can be made superconducting by annealing it in Se and O vapors. The current lore is that these chalcogen vapors induce superconductivity by removing the magnetic excess Fe atoms. To investigate this phenomenon we performed a combination of magnetic susceptibility, specific heat and transport measurements together with scanning tunneling microscopy and spectroscopy and density functional theory calculations on Fe_1+yTe_1-xSe_x treated with Te vapor. We conclude that the main role of the Te vapor is to quench the magnetic moments of the excess Fe atoms by forming FeTe_m (m ≥ 1) complexes. We show that the remaining FeTe_m complexes are still damaging to the superconductivity and therefore that their removal potentially could further improve superconductive properties in these compounds.

Excess-iron driven spin glass phase in Fe_{1 + y}Te_{1 – x}Se_x

Journal Article Tian, Long ; Liu, Panpan ; Hong, Tao ; ... - Chinese Physics B

The iron-chalcogenide superconductor FeTe_1–xSe_x displays a variety of exotic features distinct from iron pnictides. Although much effort has been devoted to understanding the interplay between magnetism and superconductivity near x = 0.5, the existence of a spin glass phase with short-range magnetic order in the doping range (x ~ 0.1–0.3) has rarely been studied. Here, we use DC/AC magnetization and (quasi) elastic neutron scattering to confirm the spin-glass nature of the short-range magnetic order in a Fe_1.07Te_0.8Se_0.2 sample. The AC-frequency dependent spin-freezing temperature T_f generates a frequency sensitivity ΔT_f(ω)/[T_f(ω)Δlog₁₀ ω] ≈ 0.028 and the description of the critical slowing downmore »« less

Effect of Fe excess on structural, magnetic and superconducting properties of single-crystalline Fe{sub 1+x}Te{sub 1-y}Se{sub y}

Journal Article Viennois, R ; Giannini, E ; Marel, D van der ; ... - Journal of Solid State Chemistry

Single crystals of Fe{sub 1+x}Te{sub 1-y}Se{sub y} have been grown with a controlled Fe excess and Se doping, and the crystal structure has been refined for various compositions. The systematic investigation of magnetic and superconducting properties as a function of the structural parameters shows how the material can be driven into various ground states, depending on doping and the structural modifications. Our results prove that the occupation of the additional Fe site, Fe2, enhances the spin localization. By reducing the excess Fe, the antiferromagnetic ordering is weakened, and the superconducting ground state is favored. We have found that both Femore »« less

Coexistence of superconductivity and short-range double-stripe spin correlations in Te-vapor annealed ${FeTe}_{1 - x} {Se}_{x}$ ( $x \leq 0.2$ )

Journal Article Xu, Zhijun ; Schneeloch, J. A. ; Yi, Ming ; ... - Physical Review B

In as-grown bulk crystals of Fe_1+yTe_1-xSe_x with x≲0.3, excess Fe (y>0) is inevitable and correlates with a suppression of superconductivity. At the same time, there remains the question as to whether the character of the antiferromagnetic correlations associated with the enhanced anion height above the Fe planes in Te-rich samples is compatible with superconductivity. To test this, we have annealed as-grown crystals with x=0.1 and 0.2 in Te vapor, effectively reducing the excess Fe and inducing bulk superconductivity. Inelastic neutron scattering measurements reveal low-energy magnetic excitations consistent with short-range correlations of the double-stripe type; nevertheless, cooling into the superconducting statemore »« less

Electronic properties of the bulk and surface states of Fe_1+yTe_1-xSe_x

Journal Article Li, Yangmu ; Zaliznyak, Igor A. ; Zaki, Nader ; ... - Nature Materials

The idea of employing non-Abelian statistics for error-free quantum computing ignited interest in reports of topological surface superconductivity and Majorana zero modes (MZMs) in FeTe_0.55Se_0.45. However, the topological features and superconducting properties are not observed uniformly across the sample surface. The understanding and practical control of these electronic inhomogeneities present a prominent challenge for potential applications. Here, we combine neutron scattering, scanning angle-resolved photoemission spectroscopy, and microprobe composition and resistivity measurements to characterize the electronic state of Fe_1+yTe_1-xSe_x. We establish a phase diagram in which the superconductivity is observed only at sufficiently low Fe concentration, in association with distinct antiferromagneticmore »« less
