Nematic State in CeAuSb 2

doi:10.1103/PhysRevX.10.011035

Title: Nematic State in ${CeAuSb}_{2}$

Abstract

At ambient pressure and zero field, tetragonal CeAuSb₂ hosts stripe antiferromagnetic order at T_N= 6.3 K. Here, we first show via bulk thermodynamic probes and x-ray diffraction measurements that this magnetic order is connected with a structural phase transition to a superstructure that likely breaks C₄ symmetry, thus signaling nematic order. The temperature-field-pressure phase diagram of CeAuSb₂ subsequently reveals the emergence of additional ordered states under applied pressure at a multicritical point. Our phenomenological model supports the presence of a vestigial nematic phase in CeAuSb₂ akin to iron-based high-temperature superconductors; however, superconductivity, if present, remains to be discovered.

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 structural distortion thatmore »« less

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.

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
