Title: Observation of an emergent coherent state in the iron-based superconductor ${KFe}_{2} {As}_{2}$

Abstract

The ab-plane optical properties of KFe₂As₂ single crystals have been measured over a wide temperature and frequency range. Below T*≃155 K, where this material undergoes an incoherentcoherent crossover, a new coherent response emerges in the optical conductivity. A spectral weight analysis suggests that this new feature originates from high-energy bound states. Below about ≃75 K the scattering rate for this new feature is quadratic in temperature, indicating a Fermiliquid response. Theoretical calculations suggest this crossover is dominated by the d_xy orbital. Our results indicate Kondo-type screening is the likely mechanism for the incoherent-coherent crossover in hole-overdoped KFe₂As₂.

Pressure dependence of coherence-incoherence crossover behavior in ${KFe}_{2} {As}_{2}$ observed by resistivity and ${}^{75}{As}$ -NMR/NQR

Journal Article Wiecki, P. ; Taufour, V. ; Chung, D. Y. ; ... - Physical Review B

We present the results of ⁷⁵As nuclear magnetic resonance (NMR), nuclear quadrupole resonance (NQR), and resistivity measurements in KF_e2 As₂ under pressure (p). The temperature dependence of the NMR shift, nuclear spin-lattice relaxation time (T₁), and resistivity show a crossover between a high-temperature incoherent, local-moment behavior and a low-temperature coherent behavior at a crossover temperature (T*). T* is found to increase monotonically with pressure, consistent with increasing hybridization between localized 3d orbital-derived bands with the itinerant electron bands. No anomaly in T* is seen at the critical pressure p_c= 1.8 GPa where a change of slope of the superconducting (SC)more »« less

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.

Intertwined Magnetic and Nematic Orders in Semiconducting ${KFe}_{0.8} {Ag}_{1.2} {Te}_{2}$

Journal Article Song, Yu ; Cao, Huibo ; Chakoumakos, B. C. ; ... - Physical Review Letters

Superconductivity in the iron pnictides emerges from metallic parent compounds exhibiting intertwined stripe-type magnetic order and nematic order, with itinerant electrons suggested to be essential for both. Here we use x-ray and neutron scattering to show that a similar intertwined state is realized in semiconducting KFe_0.8Ag_1.2Te₂ (K₅Fe₄Ag₆Te₁₀) without itinerant electrons. We find that Fe atoms in KFe_0.8Ag_1.2Te₂ form isolated 2×2 blocks, separated by nonmagnetic Ag atoms. Long-range magnetic order sets in below T_N ≈ 35 K, with magnetic moments within the 2×2 Fe blocks ordering into the stripe-type configuration. A nematic order accompanies the magnetic transition, manifest as a structuralmore »« less

Journal Article Nakajima, Yasuyuki ; Wang, Renxiong ; Metz, Tristin ; ... - Physical Review. B, Condensed Matter and Materials Physics

Here, we report a high-pressure study of simultaneous low-temperature electrical resistivity and Hall effect measurements on high quality single-crystalline KFe₂As₂ using designer diamond anvil cell techniques with applied pressures up to 33 GPa. In the low pressure regime, we show that the superconducting transition temperature T_c finds a maximum onset value of 7 K near 2 GPa, in contrast to previous reports that find a minimum T_c and reversal of pressure dependence at this pressure. Upon applying higher pressures, this T_c is diminished until a sudden drastic enhancement occurs coincident with a first-order structural phase transition into a collapsed tetragonalmore »« less

Optimization of the crystal growth of the superconductor ${CaKFe}_{4} {As}_{4}$ from solution in the $FeAs - {CaFe}_{2} {As}_{2} - {KFe}_{2} {As}_{2}$ system

Journal Article Meier, W. R. ; Kong, T. ; Bud'ko, S. L. ; ... - Physical Review Materials

Measurements of the anisotropic properties of single crystals play a crucial role in probing the physics of new materials. Determining a growth protocol that yields suitable high-quality single crystals can be particularly challenging for multicomponent compounds. Here we present a case study of how we refined a procedure to grow single crystals of CaKFe₄As₄ from a high temperature, quaternary liquid solution rich in iron and arsenic (“FeAs self-flux”). Temperature dependent resistance and magnetization measurements are emphasized, in addition to the x-ray diffraction, to detect intergrown CaKFe₄As₄, CaFe₂As₂, and KFe₂As₂ within what appear to be single crystals.
