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

Abstract

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.

Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in ${BaFe}_{2 - x} T_{x} {As}_{2}$ ( $T = Co, Ni$ )

Journal Article Tam, David W. ; Song, Yu ; Man, Haoran ; ... - Physical Review B

In this paper, we use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFe₂As₂ and its Co- and Ni-substituted members near optimal superconductivity. In the low-temperature AF ordered state, uniaxial pressure necessary to detwin the orthorhombic crystals also increases the magnetic ordered moment, reaching an 11% increase under 40 MPa for BaFe_1.9Co_0.1As₂, and a 15% increase for BaFe_1.915Ni_0.085As₂. We also observe an increase of the AF ordering temperature (T_N) of about 0.25 K/MPa in all compounds, consistent with density functional theory calculations that reveal better Fermi surfacemore »« less

NMR study of nematic spin fluctuations in a detwinned single crystal of underdoped $Ba {({Fe}_{1 ₋ x} {Co}_{x})}_{2} {As}_{2}$

Journal Article Kissikov, T. ; Dioguardi, A. P. ; Timmons, E. I. ; ... - Physical Review B

We report the experimental details of how mechanical detwinning can be implemented in tandem with high sensitivity nuclear magnetic resonance measurements and use this setup to measure the inplane anisotropy of the spin-lattice relaxation rate in underdoped Ba(Fe_1-xCo_x)₂As₂ with x = 0:048. The anisotropy reaches a maximum of 30% at TN, and the recovery data reveal that the glassy behavior of the spin fluctuations present in the twinned state persist in the fully detwinned crystal. A theoretical model is presented to describe the spin-lattice relaxation rate in terms of anisotropic nematic spin fluctuations.

Hedgehog Spin-Vortex Crystal Antiferromagnetic Quantum Criticality in $CaK ({Fe}_{1 - x} {Ni}_{x})_{4} {As}_{4}$ Revealed by NMR

Journal Article Ding, Q. -P. ; Meier, W. R. ; Cui, J. ; ... - Physical Review Letters

Two ordering states, antiferromagnetism and nematicity, have been observed in most iron-based superconductors (SCs). In contrast to those SCs, the newly discovered SC CaK(Fe_1-xNi_x)₄As₄ exhibits an antiferromagnetic (AFM) state, called hedgehog spin-vortex crystal structure, without nematic order, providing the opportunity for the investigation into the relationship between spin fluctuations and SC without any effects of nematic fluctuations. Our ⁷⁵As nuclear magnetic resonance studies on CaK(Fe_1-xNi_x)₄As₄ (0≤ x ≤ 0.049) revealed that CaKFe₄As₄ is located close to a hidden hedgehog SVC AFM quantum-critical point (QCP). The magnetic QCP without nematicity in CaK(Fe_1-xNi_x)₄As₄ highlights the close connection of spin fluctuations and superconductivitymore »« less

Magnetoresistance Scaling Reveals Symmetries of the Strongly Correlated Dynamics in ${BaFe}_{2} ({As}_{1 - x} P_{x})_{2}$

Journal Article Hayes, Ian M. ; Hao, Zeyu ; Maksimovic, Nikola ; ... - Physical Review Letters

The phenomenon of T-linear resistivity commonly observed in a number of strange metals has been widely seen as evidence for the breakdown of the quasiparticle picture of metals. This study shows that a recently discovered H/T scaling relationship in the magnetoresistance of the strange metal BaFe₂(As_1-xP_x)₂ is independent of the relative orientations of current and magnetic field. Rather, its magnitude and form depend only on the orientation of the magnetic field with respect to a single crystallographic axis: the direction perpendicular to the magnetic iron layers. In this work, this finding suggests that the magnetotransport scaling does not originate frommore »« less

From Ising Resonant Fluctuations to Static Uniaxial Order in Antiferromagnetic and Weakly Superconducting $CeCo ({In}_{1 - x} {Hg}_{x})_{5} (x = 0.01)$

Journal Article Stock, C. ; Rodriguez-Rivera, J. A. ; Schmalzl, K. ; ... - Physical Review Letters

CeCo (In_0.990Hg_0.010)₅ is a charge doped variant of the d-wave CoCoIn₅ superconductor with coexistent antiferromagnetic and superconducting transitions occurring at T_N = 3.4 and T_c = 1.4 K, respectively. We use neutron diffraction and spectroscopy to show that the magnetic resonant fluctuations present in the parent superconducting phase are replaced by collinear c -axis magnetic order with three-dimensional Ising critical fluctuations. No low-energy transverse spin fluctuations are observable in this doping-induced antiferromagnetic phase and the dynamic resonant spectral weight predominately shifts to the elastic channel. Static (τ > 0.2 ns) collinear Ising order is proximate to superconductivity in CeCoIn₅ andmore »« less
