Title: Disorder-Driven Transition from $s_{\pm}$ to $s_{+ +}$ Superconducting Order Parameter in Proton Irradiated $Ba ({Fe}_{1 - x} {Rh}_{x})_{2} {As}_{2}$ Single Crystals

Abstract

Here, microwave measurements of the London penetration depth and critical temperature T _c were used to show evidence of a disordered-driven transition from s _± to s ₊₊ order parameter symmetry in optimally doped Ba(Fe _1–xRh _x) ₂As ₂ single crystals, where disorder was induced by means of 3.5 MeV proton irradiation. Signatures of such a transition, as theoretically predicted, are found as a drop in the low-temperature values of the London penetration depth and a virtually disorder-independent superconducting T _c. We show how these experimental observations can be described by multiband Eliashberg calculations in which the effect of disorder is accounted for in a suitable way. To this aim, an effective two-band approach is adopted, allowing us to treat disorder in a range between the Born approximation and the unitary limit.

Effect of Electron Irradiation on Superconductivity in Single Crystals of $Ba ({Fe}_{1 - x} {Ru}_{x})_{2} {As}_{2}$ ( $x = 0.24$ )

Journal Article Prozorov, R. ; Kończykowski, M. ; Tanatar, M. A. ; ... - Physical Review. X

A single crystal of isovalently substituted Ba(Fe _1-xRu _x) ₂As ₂ (x=0.24) is sequentially irradiated with 2.5 MeV electrons up to a maximum dose of 2.1×10 ¹⁹ e ^-/cm ². The electrical resistivity is measured in situ at T=22 K during the irradiation and ex situ as a function of temperature between subsequent irradiation runs. Upon irradiation, the superconducting transition temperature T _c decreases and the residual resistivity ρ0 increases. We find that electron irradiation leads to the fastest suppression of T _c compared to other types of artificially introduced disorder, probably due to the strong short-range potential of themore »« less

Structural and Magnetic Phase Transitions near Optimal Superconductivity in ${{BaFe}_{2} ({As}_{1 - x} P_{x})}_{2}$

Journal Article Hu, Ding ; Lu, Xingye ; Zhang, Wenliang ; ... - Physical Review Letters

We use nuclear magnetic resonance (NMR), high-resolution x-ray, and neutron scattering studies to study structural and magnetic phase transitions in phosphorus-doped BaFe2(As1-xPx)(2). Previous transport, NMR, specific heat, and magnetic penetration depth measurements have provided compelling evidence for the presence of a quantum critical point (QCP) near optimal superconductivity at x = 0.3. However, we show that the tetragonal-to-orthorhombic structural (T-s) and paramagnetic to antiferromagnetic (AF, T-N) transitions in BaFe2(As1-xPx)(2) are always coupled and approach T-N approximate to T-s >= T-c (approximate to 29 K) for x = 0.29 before vanishing abruptly for x >= 0.3. These results suggest that AFmore »« less

Unconventional Charge Density Wave Order in the Pnictide Superconductor $Ba ({Ni}_{1 - x} {Co}_{x})_{2} {As}_{2}$

Journal Article Lee, Sangjun ; de la Peña, Gilberto ; Sun, Stella X. -L. ; ... - Physical Review Letters

Ba(Ni _1–xCo _x) ₂As ₂ is a structural homologue of the pnictide high temperature superconductor, Ba(Fe _1–xCo _x) ₂As ₂, in which the Fe atoms are replaced by Ni. Superconductivity is highly suppressed in this system, reaching a maximum T_c = 2.3 K, compared to 24 K in its iron-based cousin, and the origin of this T_c suppression is not known. Using x-ray scattering, we show that Ba(Ni _1–xCo _x) ₂As ₂ exhibits a unidirectional charge density wave (CDW) at its triclinic phase transition. The CDW is incommensurate, exhibits a sizable lattice distortion, and is accompanied by the appearance ofmore »« less

V ₂O ₃ famously features all four combinations of paramagnetic versus antiferromagnetic and metallic versus insulating states of matter in response to percent-level doping, pressure in the GPa range, and temperature below 300 K. Using time-of-flight neutron spectroscopy combined with density functional theory calculations of magnetic interactions, we have mapped and analyzed the inelastic magnetic neutron scattering cross section over a wide range of energy and momentum transfer in the chromium-stabilized antiferromagnetic and paramagnetic insulating phases. Our results reveal an important magnetic frustration and degeneracy of the paramagnetic insulating phase which is relieved by the rhombohedral-to-monoclinic transition at T_N =more »« less
