Title: Observation of non-Fermi liquid behavior in hole-doped LiFe_1-x V_xAs

Abstract

Here we synthesized a series of V-doped LiFe_1₋xV_xAs single crystals. The superconducting transition temperature T_c of LiFeAs decreases rapidly at a rate of 7 K per 1% V. The Hall coefficient of LiFeAs switches from negative to positive with 4.2% V doping, showing that V doping introduces hole carriers. This observation is further confirmed by the evaluation of the Fermi surface volume measured by angle-resolved photoemission spectroscopy (ARPES), from which a 0.3 hole doping per V atom introduced is deduced. Interestingly, the introduction of holes does not follow a rigid band shift. We also show that the temperature evolution of the electrical resistivity as a function of doping is consistent with a crossover from a Fermi liquid to a non-Fermi liquid. Our ARPES data indicate that the non-Fermi liquid behavior is mostly enhanced when one of the hole d_xz/dyz Fermi surfaces is well nested by the antiferromagnetic wave vector to the inner electron Fermi surface pocket with the d_xy orbital character. In conclusion, the magnetic susceptibility of LiFe_1₋xV_xAs suggests the presence of strong magnetic impurities following V doping, thus providing a natural explanation to the rapid suppression of superconductivity upon V doping.

Orbital Selective Spin Excitations and their Impact on Superconductivity of ${LiFe}_{1 - x} {Co}_{x} As$

Journal Article Li, Yu ; Yin, Zhiping ; Wang, Xiancheng ; ... - Physical Review Letters

We use neutron scattering to study spin excitations in single crystals of LiFe_0.88Co_0.12As, which is located near the boundary of the superconducting phase of LiFe_1-xCo_xAs and exhibits non- Fermi-liquid behavior indicative of a quantum critical point. By comparing spin excitations of LiFe_0.88Co_0.12As with a combined density functional theory (DFT) and dynamical mean field theory (DMFT) calculation, we conclude that wave-vector correlated low energy spin excitations are mostly from the dxy orbitals, while high-energy spin excitations arise from the dyz and dxz orbitals. Unlike most iron pnictides, the strong orbital selective spin excitations in LiFeAs family cannot be described by anisotropicmore »« less

Potential Lifshitz transition at optimal substitution in nematic pnictide Ba_1xSr_xNi₂As₂

Journal Article Narayan, Dushyant M. ; Hao, Peipei ; Kurleto, Rafał ; ... - Science Advances

BaNi₂As₂ is a structural analog of the pnictide superconductor BaFe₂As₂, which, like the iron-based superconductors, hosts a variety of ordered phases including charge density waves (CDWs), electronic nematicity, and superconductivity. Upon isovalent Sr substitution on the Ba site, the charge and nematic orders are suppressed, followed by a sixfold enhancement of the superconducting transition temperature (T_c). To understand the mechanisms responsible for enhancement of T_c, we present high-resolution angle-resolved photoemission spectroscopy (ARPES) measurements of the Ba_1-xSr_xNi₂As₂ series, which agree well with our density functional theory (DFT) calculations throughout the substitution range. Analysis of our ARPES-validated DFT results indicates a Lifshitzmore »« less

Spin dynamics and orbital-antiphase pairing symmetry in iron-based superconductors

Journal Article Yin, Z. Ping ; Haule, K. ; Kotliar, G. - Nature Physics

The symmetry of the wave function describing the Cooper pairs is one of the most basic quantities in a superconductor yet its measurement in the iron-based superconductors has proved to be very difficult. The complex multi-band nature of these materials makes the interplay of superconductivity with spin and orbital dynamics very intriguing, leading to very material dependent magnetic excitations, and pairing symmetries. In this work we use first-principles many-body method, including ab initio determined two-particle vertex function, to study the spin dynamics and superconducting pairing symmetry in a large number of iron-based superconductors. In iron compounds with high transition temperature,more »« less

Angle Resolved Photoemission Spectroscopy Studies of the Mott Insulator to Superconductor Evolution in Ca2-xNaxCuO2Cl2

Technical Report Shen, Kyle Michael

It is widely believed that many of the exotic physical properties of the high-T{sub c} cuprate superconductors arise from the proximity of these materials to the strongly correlated, antiferromagnetic Mott insulating state. Therefore, one of the fundamental questions in the field of high-temperature superconductivity is to understand the insulator-to-superconductor transition and precisely how the electronic structure of Mott insulator evolves as the first holes are doped into the system. This dissertation presents high-resolution, doping dependent angle-resolved photoemission (ARPES) studies of the cuprate superconductor Ca{sub 2-x}Na{sub x}CuO{sub 2}Cl{sub 2}, spanning from the undoped parent Mott insulator to a high-temperature superconductor withmore »« less

Spin-Fluctuation-Induced Non-Fermi-Liquid Behavior with Suppressed Superconductivity in ${LiFe}_{1 - x} {Co}_{x} As$

Journal Article Dai, Y. M. ; Miao, H. ; Xing, L. Y. ; ... - Physical Review. X

A series of LiFe_1–xCo_xAs compounds with different Co concentrations by transport, optical spectroscopy, angle-resolved photoemission spectroscopy, and nuclear magnetic resonance. We observe a Fermi-liquid to non-Fermi-liquid to Fermi-liquid (FL-NFL-FL) crossover alongside a monotonic suppression of the superconductivity with increasing Co content. In parallel to the FL-NFL-FL crossover, we find that both the low-energy spin fluctuations and Fermi surface nesting are enhanced and then diminished, strongly suggesting that the NFL behavior in LiFe_1–xCo_xAs is induced by low-energy spin fluctuations that are very likely tuned by Fermi surface nesting. Our study reveals a unique phase diagram of LiFe_1–xCo_xAs where the region ofmore »« less
