Title: Role of magnetism in superconductivity of BaFe₂As₂: Study of 5d Au-doped crystals

Abstract

We investigate properties of BaFe₂As₂ (122) single crystals upon gold doping, which is the transition metal with the highest atomic weight. The Au substitution into the FeAs-planes of 122 crystal structure (Au-122) is only possible up to a small amount of ~3%. We find that 5d is more effective in reducing magnetism in 122 than its counter 3d Cu, and this relates to superconductivity. We provide evidence of short-range magnetic fluctuations and local lattice inhomogeneities that may prevent strong percolative superconductivity in Ba(Fe_1-xAu_x)2As₂.

Superconductivity with T_c ≈ 7 K under pressure for Cu- and Au-doped BaFe₂As₂

Journal Article Li, Li ; Parker, David S. ; Cao, Huibo B. ; ... - Journal of Physics. Condensed Matter

It is noteworthy that chemical substitution of BaFe₂As₂ (122) with the noble elements Cu and Au gives superconductivity with a maximum T_c ≈ 3 K, while Ag substitution (Ag-122) stays antiferromagnetic. For Ba(Fe_1–xTM_x)₂As₂, TM = Cu, Au, or Ag, and by doping an amount of x = 0.04, a-lattice parameter slightly increases (0.4%) for all TM dopants, while c-lattice decreases (–0.2%) for TM = Cu, barely moves (0.05%) for Au, and increases (0.2%) for Ag. Despite the naive expectation that the noble elements of group 11 should affect the quantum properties of 122 similarly, they produce significant differences extending tomore »« less

Deep data mining in a real space: Separation of intertwined electronic responses in a lightly doped BaFe₂As₂

Journal Article Ziatdinov, Maxim ; Maksov, Artem ; Li, Li ; ... - Nanotechnology

Electronic interactions present in material compositions close to the superconducting dome play a key role in the manifestation of high-T _c superconductivity. In many correlated electron systems, however, the parent or underdoped states exhibit strongly inhomogeneous electronic landscape at the nanoscale that may be associated with competing, coexisting, or intertwined chemical disorder, strain, magnetic, and structural order parameters. Here we demonstrate an approach based on a combination of scanning tunneling microscopy/spectroscopy and advanced statistical learning for an automatic separation and extraction of statistically significant electronic behaviors in the spin density wave regime of a lightly (~1%) gold-doped BaFe₂As₂. Lastly, wemore »« less

Unusually high critical current of clean P-doped BaFe{sub 2}As{sub 2} single crystalline thin film

Journal Article Kurth, F., E-mail: fritz.kurth@ifw-dresden.de ; Engelmann, J. ; Schultz, L. ; ... - Applied Physics Letters

Microstructurally clean, isovalently P-doped BaFe{sub 2}As{sub 2} (Ba-122) single crystalline thin films have been prepared on MgO (001) substrates by molecular beam epitaxy. These films show a superconducting transition temperature (T{sub c}) of over 30 K although P content is around 0.22, which is lower than the optimal one for single crystals (i.e., 0.33). The enhanced T{sub c} at this doping level is attributed to the in-plane tensile strain. The strained film shows high transport self-field critical current densities (J{sub c}) of over 6 MA/cm{sup 2} at 4.2 K, which are among the highest for Fe based superconductors (FeSCs).

Superconductor-in-an-Hour: Spark Plasma Synthesis of Co- and Ni-Doped BaFe₂As₂

Journal Article Zaikina, Julia V. ; Kwong, Ming Yin ; Baccam, Brandon ; ... - Chemistry of Materials

In this work, BaFe₂As₂ superconductors doped with Co or Ni were synthesized by heat treatment of the reactive BaH₂ precursor and elemental Fe, Co, Ni, and As in a sealed niobium container. The hydride route provides better mixing of the starting materials, resulting in faster preparation of the target phases. The hydrogen gas evolved during sintering facilitates the preparation of the oxygen-free powders. Using powder X-ray diffraction (PXRD), including low-temperature synchrotron PXRD, it was shown that this route leads to successful doping of the Co (Ni) dopant and that the actual dopant content in the produced powdered samples of BaFe_2–xCo_xAs₂more »« less

Effects of vanadium doping on BaFe₂As₂

Journal Article Li, Xing-Guang ; Sheng, Jie-Ming ; Tian, Cong-Kuan ; ... - Europhysics Letters (Online)

In this paper, we report an investigation of the structural, magnetic and electronic properties of Ba(Fe_1-x V _x )₂As₂ using x-ray, transport, magnetic susceptibility and neutron scattering measurements. The vanadium substitutions in Fe sites are possible up to ~40%. Hall effect measurements indicate strong hole-doping effect through V doping, while no superconductivity is observed in all samples down to 2 K. The antiferromagnetic and structural transition temperature of BaFe₂As₂ is gradually suppressed to finite temperature, then vanishes at $x=0.245$ with the emergence of spin glass behavior, suggesting an avoided quantum critical point (QCP). Finally, our results demonstrate that the avoidedmore »« less
