Title: Spin excitations in optimally P-doped ${BaFe}_{2} {({As}_{0.7} P_{0.3})}_{2}$ superconductor

Abstract

We use inelastic neutron scattering to study temperature and energy dependence of spin excitations in optimally P-doped BaFe₂(As_0:7P_0:3)₂ superconductor (T_c = 30 K) throughout the Brillouin zone. In the undoped state, spin waves and paramagnetic spin excitations of BaFe₂As₂ stem from antiferromagnetic (AF) ordering wave vector QAF = ( 1; 0) and peaks near zone boundary at ( 1; 1) around 180 meV. Replacing 30% As by smaller P to induce superconductivity, low-energy spin excitations of BaFe₂(As_0:7P_0:3)₂ form a resonance in the superconducting state and high-energy spin excitations now peaks around 220 meV near ( 1; 1). These results are consistent with calculations from a combined density functional theory and dynamical mean field theory, and suggest that the decreased average pnictogen height in BaFe₂(As_0:7P_0:3)₂ reduces the strength of electron correlations and increases the effective bandwidth of magnetic excitations.

Superconducting gap evolution in overdoped ${BaFe}_{2} {({As}_{1 - x} P_{x})}_{2}$ single crystals through nanocalorimetry

Journal Article Campanini, D. ; Diao, Z. ; Fang, L. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report on specific heat measurements on clean overdoped BaFe₂(As_1-xP_x)₂ single crystals performed with a high resolution membrane-based nanocalorimeter. A nonzero residual electronic specific heat coefficient at zero temperature γ_r = C/T |_{T→ 0} is seen for all doping compositions, indicating a considerable fraction of the Fermi surface ungapped or having very deep minima. The remaining superconducting electronic specific heat is analyzed through a two-band s-wave alpha model in order to investigate the gap structure. Close to optimal doping we detect a single zero-temperature gap of Δ₀ ~ 5.3 meV, corresponding to Δ₀/k_BT_c ~ 2.2. Increasing the phosphorus concentration x, the main gap reduces till a value of Δ₀ ~ 1.9 meV for x = 0.55 and a second weaker gap becomes evident. From the magnetic field effect on γ_r, all samples however show similar behavior γ_r(H)more »« less

Journal Article Allred, J. M. ; Taddei, K. M. ; Bugaris, D. E. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We present neutron dffraction analysis of BaFe₂(As_1-xP_x)₂ over a wide temperature (10 to 300 K) and compositional (0.11 < x < 0.79) range, including the normal state, the magnetically ordered state, and the superconducting state. The paramagnetic to spin-density wave and orthorhombic to tetragonal transitions are first order and coincident within the sensitivity of our measurements (~ 0:5 K). Extrapolation of the orthorhombic order parameter down to zero suggests that structural quantum criticality cannot exist at compositions higher than x = 0.28, which is much lower than values determined using other methods, but in good agreement with our observations ofmore »« less

We investigate the electronic specific heat of superoptimally substituted BaFe₂(As_1-x P_x)₂ single crystals in the superconducting state using high-resolution nanocalorimetry. From the measurements, we extract the substitution dependence of the condensation energy, superconducting gap Δ, and related microscopic parameters.

Doping dependence of the specific heat of single-crystal BaFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$

Journal Article Chaparro, C. ; Fang, L. ; Claus, H. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We present specific heat measurements on a series of BaFe 2 (As 1 - x P x ) 2 single crystals with phosphorous doping ranging from x = 0.3 to x = 0.55. Our results reveal that BaFe 2 (As 1 - x P x ) 2 follows the scaling Δ C / T c ≈ T 2 c remarkably well. The clean-limit nature of this material imposes additional restraints on theories aimed at explaining the scaling. Furthermore, we find that the Ginzburg-Landau parameter decreases significantly with doping whereas the superconducting anisotropy is Γ ≈ 2.6, independent of doping.

NMR evidence for inhomogeneous nematic fluctuations in ${BaFe}_{2} ({As}_{1 - x} P_{x})_{2}$

Journal Article Dioguardi, A. P. ; Kissikov, T. ; Lin, C. H. ; ... - Physical Review Letters

We present evidence for nuclear spin-lattice relaxation driven by glassy nematic fluctuations in isovalent P-doped BaFe₂As₂ single crystals. Both the ⁷⁵As and ³¹P sites exhibit a stretched-exponential relaxation similar to the electron-doped systems. By comparing the hyperfine fields and the relaxation rates at these sites we find that the As relaxation cannot be explained solely in terms of magnetic spin fluctuations. We demonstrate that nematic fluctuations couple to the As nuclear quadrupolar moment and can explain the excess relaxation. Finally, these results suggest that glassy nematic dynamics are a common phenomenon in the ironbased superconductors.
