Title: Continuous excitations of the triangular-lattice quantum spin liquid YbMgGaO₄

Abstract

A quantum spin liquid (QSL) is an exotic state of matter in which electrons’ spins are quantum entangled over long distances, but do not show magnetic order in the zero-temperature limit. The observation of QSL states is a central aim of experimental physics, because they host collective excitations that transcend our knowledge of quantum matter; however, examples in real materials are scarce. We report neutron-scattering experiments on YbMgGaO₄, a QSL candidate in which Yb³⁺ ions with effective spin-1/2 occupy a triangular lattice. Furthermore, our measurements reveal a continuum of magnetic excitations—the essential experimental hallmark of a QSL7—at very low temperature (0.06 K). The origin of this peculiar excitation spectrum is a crucial question, because isotropic nearest-neighbour interactions do not yield a QSL ground state on the triangular lattice. In using measurements the field-polarized state, we identify antiferromagnetic next-nearest-neighbour interactions spin-space anisotropies and chemical disorder between the magnetic layers as key ingredients in YbMgGaO₄.

Survival of itinerant excitations and quantum spin state transitions in YbMgGaO₄ with chemical disorder

Journal Article Rao, X. ; Hussain, G. ; Huang, Q. ; ... - Nature Communications

A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question is whether the QSL survives disorder or the disorder leads to a “spin-liquid-like” state, such as the proposed random-singlet (RS) state. Since disorder is a standard feature of most QSL candidates, this question represents a major challenge for QSL candidates. YbMgGaO₄, a triangular lattice antiferromagnet with effective spin-1/2 Yb³⁺ions, is an ideal system to address this question, since it shows no long-range magnetic ordering with Mg/Ga site disorder. Despite the intensive study, it remains unresolvedmore »« less

Hierarchy of Exchange Interactions in the Triangular-Lattice Spin Liquid ${YbMgGaO}_{4}$

Journal Article Zhang, Xinshu ; Mahmood, Fahad ; Daum, Marcus ; ... - Physical Review. X

The spin-1/2 triangular lattice antiferromagnet YbMgGaO₄ has attracted attention recently as a quantum spin-liquid candidate with the possible presence of off-diagonal anisotropic exchange interactions induced by spin-orbit coupling. Whether a quantum spin liquid is stabilized or not depends on the interplay of various exchange interactions with chemical disorder that is inherent to the layered structure of the compound. We combine time-domain terahertz spectroscopy and inelastic neutron scattering measurements in the field-polarized state of YbMgGaO₄ to obtain better insight of its exchange interactions. Terahertz spectroscopy in this fashion functions as a high-field electron spin resonance and probes the spin-wave excitations atmore »« less

Experimental signatures of a three-dimensional quantum spin liquid in effective spin-1/2 Ce₂Zr₂O₇ pyrochlore

Journal Article Gao, Bin ; Chen, Tong ; Tam, David W. ; ... - Nature Physics

A quantum spin liquid is a state of matter where unpaired electrons’ spins, although entangled, do not show magnetic order even at the zero temperature. The realization of a quantum spin liquid is a long-sought goal in condensed-matter physics. Although neutron scattering experiments on the two-dimensional spin-1/2 kagome lattice ZnCu₃(OD)₆Cl₂ and triangular lattice YbMgGaO₄ have found evidence for the hallmark of a quantum spin liquid at very low temperature (a continuum of magnetic excitations), the presence of magnetic and non-magnetic site chemical disorder complicates the interpretation of the data. Recently, the three-dimensional Ce³⁺ pyrochlore lattice Ce₂Sn₂O₇ has been suggested asmore »« less

Strong quantum fluctuations in a quantum spin liquid candidate with a Co-based triangular lattice

Journal Article Zhong, Ruidan ; Guo, Shu ; Xu, Guangyong ; ... - Proceedings of the National Academy of Sciences of the United States of America

Currently under active study in condensed matter physics, both theoretically and experimentally, are quantum spin liquid (QSL) states, in which no long-range magnetic ordering appears at low temperatures due to strong quantum fluctuations of the magnetic moments. The existing QSL candidates all have their intrinsic disadvantages, however, and solid evidence for quantum fluctuations is scarce. Here, we report a previously unreported compound, Na2BaCo(PO4)2, a geometrically frustrated system with effective spin-1/2 local moments for Co2+ ions on an isotropic 2-dimensional (2D) triangular lattice. Magnetic susceptibility and neutron scattering experiments show no magnetic ordering down to 0.05 K. Thermodynamic measurements show thatmore »« less

Spin liquid state in the disordered triangular lattice Sc₂Ga₂CuO₇ revealed by NMR

Journal Article Khuntia, P. ; Kumar, R. ; Mahajan, A. V. ; ... - Physical Review B

We present microscopic magnetic properties of a two-dimensional triangular lattice Sc₂Ga₂CuO₇, consisting of single and double triangular Cu planes. An antiferromagnetic (AFM) exchange interaction J/k_B ≈ 35 K between Cu²⁺ (S = 1/2) spins in the triangular biplane is obtained from the analysis of intrinsic magnetic susceptibility data. The intrinsic magnetic susceptibility, extracted from ⁷¹Ga NMR shift data, displays the presence of AFM short range spin correlations and remains finite down to 50 mK, suggesting a nonsinglet ground state. The nuclear spin-lattice relaxation rate (1/T₁) reveals a slowing down of Cu²⁺ spin fluctuations with decreasing T down to 100 mK.more »« less
