Title: Interplay of magnetism and superconductivity in the compressed Fe-ladder compound ${BaFe}_{2} {Se}_{3}$

Abstract

High pressure resistance, susceptibility, and Fe K β x-ray emission spectroscopy measurements were performed on Fe-ladder compound BaFe 2 Se 3 . Pressure-induced superconductivity was observed which is similar to the previously reported superconductivity in the BaFe 2 S 3 samples. The slope of local magnetic moment versus pressure shows an anomaly across the insulator-metal transition pressure in the BaFe 2 Se 3 samples. The local magnetic moment is continuously decreasing with increasing pressure, and the superconductivity appears only when the local magnetic moment value is comparable to the one in the iron-pnictide superconductors. Our results indicate that the compressed BaFe 2 C h 3 ( C h = S , Se) is a new family of iron-based superconductors. Despite the crystal structures completely different from the known iron-based superconducting materials, the magnetism in this Fe-ladder material plays a critical role in superconductivity. This behavior is similar to the other members of iron-based superconducting materials.

Pressure-driven phase transition from antiferromagnetic semiconductor to nonmagnetic metal in the two-leg ladders $A {Fe}_{2} X_{3}$ ( $A = Ba, K$ ; $X = S, Se$ )

Journal Article Zhang, Yang ; Lin, Lingfang ; Zhang, Jun -Jie ; ... - Physical Review B

The recent discovery of superconductivity in BaFe ₂S ₃ has stimulated considerable interest in 123-type iron chalcogenides. This material is the first reported iron-based two-leg ladder superconductor, as opposed to the prevailing two-dimensional layered structures of the iron superconductor family. Once the hydrostatic pressure exceeds 11 GPa, BaFe ₂S ₃ changes from a semiconductor to a superconductor below 24 K. Although previous calculations correctly explained its ground-state magnetic state and electronic structure, the pressure-induced phase transition was not successfully reproduced. In this work, our first-principles calculations show that with increasing pressure the lattice constants as well as local magnetic momentsmore »« less

Sequential structural and antiferromagnetic transitions in ${BaFe}_{2} {Se}_{3}$ under pressure

We present the discovery of superconductivity in the two-leg ladder compound BaFe ₂S ₃ has established the 123-type iron chalcogenides as a novel and interesting subgroup of the iron-based superconductor family. However, in this 123 series, BaFe ₂Se ₃ is an exceptional member, with a magnetic order and crystalline structure different from all others. Recently, an exciting experiment reported the emergence of superconductivity in BaFe ₂Se ₃ at high pressure [J. Ying et al., Phys. Rev. B 95, 241109(R) (2017)]. In this paper, we report a first-principles study of BaFe ₂Se ₃. Our analysis unveils a variety of qualitative differencesmore »« less

Gradual enhancement of stripe-type antiferromagnetism in the spin-ladder material ${BaFe}_{2} S_{3}$ under pressure

Journal Article Zheng, Liangliang ; Frandsen, Benjamin A. ; Wu, Changwei ; ... - Physical Review B

We report the recent discovery of pressure-induced superconductivity in BaFe ₂S ₃ and BaFe ₂Se ₃ has generated considerable interest in the 123-type iron chalcogenides. The structure of these materials features iron atoms arranged in quasi-one-dimensional ladders with either stripe-type or block-type antiferromagnetism at ambient pressure, constituting a new parent state for iron-based superconductivity in need of detailed study. Here, we report pressure-dependent neutron diffraction and muon spin relaxation/rotation measurements combined with first-principles calculations to investigate the structural, magnetic, and electronic properties of BaFe ₂S ₃ under pressure. The experimental results reveal a gradual enhancement of the stripe-type ordering temperaturemore »« less

${}^{77}{Se}$ NMR investigation of the $K_{x}$ Fe $_{2 - y}$ Se $_{2}$ high- $T_{c}$ superconductor ( $T_{c} = 33$ K)

Journal Article Torchetti, D. A. ; Fu, M. ; Christensen, D. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report comprehensive 77 Se NMR measurements on a single crystalline sample of the recently discovered FeSe-based high-temperature superconductor K x Fe 2 - y Se 2 ( T c = 33 K) in a broad temperature range up to 290 K. Despite deviations from the stoichiometric KFe 2 Se 2 composition, we observed 77 Se NMR line shapes as narrow as 4.5 kHz under a magnetic field applied along the crystal c axis, and found no evidence for co-existence of magnetic order with superconductivity. On the other hand, the 77 Se NMR line shape splits into two peaks withmore »« less

Antiferromagnetic order in ${CaK (Fe}_{1 - x} {Ni}_{x})_{4} {As}_{4}$ and its interplay with superconductivity

Journal Article Kreyssig, A. ; Wilde, John M. ; Bohmer, A. E. ; ... - Physical Review B

The magnetic order in CaK(Fe _1–xNi _x) ₄As ₄ (1144) single crystals (x = 0.051 and 0.033) has been studied by neutron diffraction. We observe magnetic Bragg peaks associated with the same propagation vectors as found for the collinear stripe antiferromagnetic (AFM) order in the related BaFe ₂As ₂ (122) compound. The AFM state in 1144 preserves tetragonal symmetry and only a commensurate, noncollinear structure with a hedgehog spin-vortex crystal (SVC) arrangement in the Fe plane and simple AFM stacking along the c direction is consistent with our observations. The SVC order is promoted by the reduced symmetry in themore »« less
