We report a comprehensive inelastic neutron-scattering study of the frustrated pyrochlore antiferromagnet MgCr2O4 in its cooperative paramagnetic regime. Theoretical modeling yields a microscopic Heisenberg model with exchange interactions up to third-nearest neighbors, which quantitatively explains all of the details of the dynamic magnetic response. We propose that our findings may provide a general framework to understand features often attributed to classical spin liquids. Neutron spectroscopy on the classical triangular-lattice frustrated antiferromagnet h -YMnO<SUB>3</SUB> reveals diffuse, gapless magnetic excitations present both far below and above the ordering temperature. This classical spin liquid. Furthermore, we find that our model remains highly frustrated despite the presence of further-neighbor (FN) interactions. We explain this result by showing that MgCr2O4 is proximate to a highly degenerate spiral-spin-liquid phase distinct from the Coulomb phase. Our results suggest that competition between nearly.
Classical spin liquid: Exact solution for the infinite-component.
In condensed matter physics, a quantum spin liquid is a phase of matter that can be formed by interacting quantum spins in certain magnetic materials. Quantum spin liquids (QSL) are generally characterized by their long-range quantum entanglement, fractionalized excitations, and absence of ordinary magnetic order. We report a comprehensive inelastic neutron-scattering study of the frustrated pyrochlore antiferromagnet MgCr_{2}O_{4} in its cooperative paramagnetic regime. Theoretical modeling yields a microscopic Heisenberg model with exchange interactions up to third-nearest neighbors, which quantitatively ex. A new classical spin liquid in which the collective flux degrees of freedom break the translation symmetry of the honeycomb lattice is reported, and the phase transition corresponds to a hidden plaquette ordering of hexagonal fluxes, which explicitly breaks the cubic symmetry.

Classical Spin Liquid Properties of the Infinite-Component Spin Vector.
Spiral spin liquids represent a special family of classical spin liquids where degenerate manifolds of spin spirals form closed contours or surfaces in momentum space. Here, we investigate the potential of spiral spin liquids to evoke quantum spin-liquid behavior when the spin magnitude is tuned from the classical limit to the quantum case.

Classical fluctuations dominate for large spins (those with a size, S, much larger than the minimum size of ½) and are driven by thermal energy. Spins can be thought of as reorienting randomly with time, cycling through different microstates. When the energy k BT becomes too small, classical fluctuations cease and the spins either freeze or order. Thermodynamic quantities and correlation functions (CFs) of the classical antiferromagnet on the kagomé lattice are studied for the exactly solvable infinite-component spin-vector model, D \to \infty. In this limit, the critical coupling of fluctuations dies out and the critical behavior simplifies, but the effect of would be Goldstone modes preventing ordering at any nonzero temperature is. Introduction - The search for quantum spin liquids (QSLs) systems to a classical spin liquid regime, characterized by an has been a central thread of correlated electron material re- infinite number of ground states. This is consistent with the re- search since their initial proposal decades ago. [1].

Hidden Plaquette Order in a Classical Spin Liquid Stabilized by Strong Off-Diagonal Exchange Phys Rev Lett. 2019 Jun 28;122 (25):257204. doi: 10.1103/PhysRevLett.122.257204. Authors Preetha Saha 1 , Zhijie Fan 1 , Depei Zhang 1 , Gia-Wei Chern 1 Affiliation 1 Department of Physics, University of Virginia, Charlottesville, Virginia 22904, USA. Here we take the example of the classical spin liquid in a frustrated magnet with novel bond-dependent interactions to investigate the classical dynamics, and critically compare it with quantum dynamics in the same system. In particular, we focus on signatures in the dynamical spin structure factor.

In contrast to the Kitaev model 13, analytical solution of the honeycomb Γ model has not been found yet 36. Previous classical studies have demonstrated that its ground state is a classical spin. Spiral spin liquids are unique classical spin liquids that occur in many frustrated spin systems, but do not comprise a new phase of matter. Owing to extensive classical ground-state degeneracy, the spins in a spiral spin liquid thermally fluctuate cooperatively from a collection of spiral configurations at low temperatures.

Title: Classical spin liquid or extended critical range in h-YMnO$_3$? Authors: Sofie Janas , Jakob Lass , Ana-Elena Tutueanu , Morten L. Haubro , Christof Niedermayer , Uwe Stuhr , Guangyong Xu , Dharmalingam Prabhakaran , Pascale P. Deen , Sonja Holm-Dahlin , Kim Lefmann. The correlated paramagnet is a simple example of a classical spin liquid. A key question is whether the local constraints have long-range consequences: is the spin liquid qualitatively. Thermodynamic quantities and correlation functions (CFs) of the classical antiferromagnet on the checkerboard lattice are studied for the exactly solvable infinite-component spin-vector model, D→∞. In contrast to conventional two-dimensional magnets with continuous symmetry showing extended short-range order at distances smaller than the correlation length, r≲ξc∝exp(T∗/T.

The best match is obtained for ourpreviously-determined FN model, with LSWT calcula-tions in striking agreement with the experimental obser-vations [Fig. 2].Our microscopic model also explains the persistence ofa classical spin-liquid in MgCr O despite FN interac-tions. Abstract We show that the honeycomb Heisenberg antiferromagnet with J 1/2 =J 2 =J 3, where J 1, J 2, and J 3 are first-, second-, and third-neighbor couplings, respectively, forms a classical spin liquid with pinch-point singularities in the structure factor at the Brillouin zone corners. We model the scattering as critical spin-spin correlations in a two-dimensional magnetic ground state, and we speculate that this may provide a general framework to understand features typically attributed to classical spin liquids.
