Title: Spin liquid state in the 3D frustrated antiferromagnet ${PbCuTe}_{2} O_{6}$ : NMR and muon spin relaxation studies

Abstract

In this study, PbCuTe₂O₆ is a rare example of a spin liquid candidate featuring a three-dimensional magnetic lattice. Strong geometric frustration arises from the dominant antiferromagnetic interaction that generates a hyperkagome network of Cu²⁺ ions although additional interactions enhance the magnetic lattice connectivity. Through a combination of magnetization measurements and local probe investigations by NMR and muon spin relaxation down to 20 mK, we provide robust evidence for the absence of magnetic freezing in the ground state. The local spin susceptibility probed by the NMR shift hardly deviates from the macroscopic one down to 1 K pointing to a homogeneous magnetic system with a low defect concentration. The saturation of the NMR shift and the sublinear power law temperature (T) evolution of the 1/T₁ NMR relaxation rate at low T point to a nonsinglet ground state favoring a gapless fermionic description of the magnetic excitations. Below 1 K a pronounced slowing down of the spin dynamics is witnessed, which may signal a reconstruction of spinon Fermi surface. Nonetheless, the compound remains in a fluctuating spin liquid state down to the lowest temperature of the present investigation.

Muon spin relaxation study of spin dynamics in the extended kagome systems ${YBaCo}_{4} O_{7 + δ} (δ = 0, 0.1)$

Journal Article Lee, S. ; Lee, Wonjun ; Lee, K. J. ; ... - Physical Review B

Here, we present muon spin relaxation (μSR) measurements of the extended kagome systems YBaCo₄O_7+δ (δ = 0,0.1), comprising two interpenetrating kagome sublattice of Co(I)³⁺ (S = 3/2) and a triangle sublattice of Co(II)²⁺ (S = 2). The zero- and longitudinal-field μ SR spectra of the stoichiometric compound YBaCo₄O₇ unveil that the triangular subsystem orders at TN = 101 K. In contrast, the muon spin relaxation rate pertaining to the kagome subsystem shows persistent spin dynamics down to T = 20 K and then a sublinear decrease λ(T ) ~ T^0.66(5) on cooling towards T = 4 K.

Journal Article Arsenault, A. ; Takahashi, S. K. ; Imai, T. ; ... - Physical Review B

¹³⁹La NMR is suited for investigations into magnetic properties of La₂CuO₄ -based cuprates in the vicinity of their magnetic instabilities, owing to the modest hyperfine interactions between ¹³⁹La nuclear spins and Cu electron spins. We report comprehensive ¹³⁹La NMR measurements on a single-crystal sample of high-T_c superconductor La 1.885 Sr 0.115 CuO₄ in a broad temperature range across the charge and spin order transitions (T charge ≃ 80 K, T neutron spin ≃ T_c = 30 K). From the high-precision measurements of the linewidth for the nuclear spin I_z = + 1 / 2 to -1/2 central transition, we show that paramagnetic line broadening sets in precisely at T charge due to enhanced spin correlations within the CuO₂ planes. Additional paramagnetic line broadening ensues below ~35 K, signaling that Cu spins in some segments of CuO₂ planes are on the verge of three-dimensional magnetic order. A static hyperfine magnetic field arising from ordered Cu moments along the ab plane, however, begins to develop only below Tmore »« less
