Title: Nematicity in the superconducting mixed state of strain detwinned underdoped Ba( ${Fe}_{1 - x} {Co}_{x})_{2} {As}_{2}$

Abstract

Evidence of nematic effects in the mixed superconducting phase of slightly underdoped Ba ( Fe_{1 - x} Co_x)₂As₂ is reported. We have found strong in-plane resistivity anisotropy for crystals in different strain conditions. For these compositions, there is no magnetic long-range order, so the description may be ascribed to the interplay between the superconducting and nematic order parameters. A piezoelectric-based apparatus is used to apply tensile or compressive strain to tune nematic domain orientation in order to examine intrinsic nematicity. Measurements are done under a rotating magnetic field, and the analysis of the angular dependence of physical quantities identifies the cases in which the sample is detwinned. Furthermore, the angular dependence of the data allows us to evaluate the effects of nematicity on the in-plane superconductor stiffness. Our results show that although nematicity contributes in a decisive way to the conduction properties, its contributions to the anisotropy properties of the stiffness of the superconducting order parameter is not as significant in these samples.

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.

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

Journal Article Guguchia, Z. ; Adachi, T. ; Shermadini, Z. ; ... - Physical Review B

High-pressure neutron powder diffraction, muon-spin rotation, and magnetization studies of the structural, magnetic, and the superconducting properties of the Ce-underdoped superconducting (SC) electron-doped cuprate system with the Nd₂ CuO₄ (the so-called T ' ) structure T ' - Pr_{1.3 - x} La_0.7 Ce_x CuO₄ with x = 0.1 are reported. A strong reduction of the in-plane and out-of-plane lattice constants is observed under pressure. However, no indication of any pressure-induced phase transition from T' to the K₂ NiF₄ (the so-called T) structure is observed up to the maximum applied pressure of p = 11 GPa.

Spin nematics break spin-rotational symmetry while maintaining time-reversal symmetry, analogous to liquid crystal nematics that break spatial rotational symmetry while maintaining translational symmetry. Although several candidate spin nematics have been proposed, the identification and characterization of such a state remain challenging because the spin-nematic order parameter does not couple directly to experimental probes.more »« less
