Theoretical study of spherical kagomé clusters in Mo72 V30 and W72 V30.

The kagome Heisenberg antiferromagnet formed by frustrated spins arranged in a lattice of corner-sharing triangles is a prime candidate for hosting a quantum spin liquid (QSL) ground state. The interplay between geometric frustration (GF) and bond disorder is studied in the Ising kagome lattice within a cluster approach. The model considers antiferromagnetic short-range couplings and long-range intercluster disordered interactions.... , potentializing the intercluster-disordered coupling and bringing the cluster spin-glass state. Using exact diagonalization for a 12-site kagome cluster, we analyzed the magnetic susceptibility and evaluated individual exchange interactions. The causes leading to the different ground states in Cs 2 Cu 3 SnF 12 and Rb 2 Cu 3 SnF 12 are discussed.

Singlet ground state and spin gap in S = 1/2 Kagomé antiferromagnet.

The susceptibility indicates a Curie-Weiss temperature ofCW' 300K; however, no magnetic order is observed down to 50 mK. Inelastic neutron scattering reveals a spectrum of low energy spin excitations with no observable gap down to 0.1 meV. The speciﬁc heat at low-Tfollows a power law temperature dependence. Spin-1/2 spherical kagomé clusters, or quantum-spin icosidodecahedrons, occurring in Mo 72 V 30 and W 72 V 30 are analyzed using the Lanczos method. Magnetic susceptibility analysis reveals that, whereas Mo 72 V 30 contains some degree of structural distortion that decreases its spin gap, the structure of W 72 V 30 can be described as a regular (non-distorted) icosidodecahedron. 2 Laboratory for Muon Spin Spectroscopy, Paul Scherrer Insititut, 5232 Villigen PSI, Switzerland. 3 LPTMC, UMR 7600 of CNRS, UPMC, Paris-Sorbonne, F-75252 Paris Cedex 05, France. 4 School of Chemistry and EaStChem, University of St. Andrews, St. Andrews, Fife KY16 9ST, United Kingdom.

Abstract: For the spherical kagome system {W 72 V 30 }, which is a magnetic cluster with 30 V 4+ ions, recent experimental and theoretical studies on the magnetization process at low temperatures have indicated that Dzyaloshinskii-Moriya interaction is an important ingredient in this material. Local spin susceptibility of the S = 1 2 kagome lattice in ZnCu 3 (OD) 6 Cl 2 Abstract We report a single-crystal 2D NMR investigation of the nearly ideal spin S= 1/2 kagome lattice ZnCu 3 (OD) 6 Cl 2. We successfully identify 2D NMR signals originating from the nearest neighbors of Cu 2+ defects occupying Zn sites.

Muon spin relaxation and susceptibility studies of the pure and diluted.

We present a comprehensive list of the ground-state energies and the spin gaps of finite Kagome clusters with up to 42 spins obtained using large-scale exact diagonalization techniques. This represents the current limit of this exact approach. For a fixed number of spins N, we study several cluster shapes under periodic boundary conditions in both directions resulting in a toroidal geometry. DOI: 10.1093/PTEP/PTU036 Corpus ID: 124590041.

Kunisada and Y. Fukumoto}, journal={Progress of Theoretical and Experimental Physics}, year={2014}, volume={2014} }. Muon spin relaxation and magnetic susceptibility measurements have been performed on the pure and diluted spin 1/2 kagomé system (CuxZn(1-x))3V2O7(OH)2 2H2O. In the pure x=1 system we found a slowing down of Cu spin fluctuations with decreasing temperature towards T approximately 1 K, followed by slow and nearly temperature-independent spin.

Vanishing spin gap in a competing spin-liquid phase in the kagome.

Combined with the magnetic field dependence of χ kagome that we observed at low temperatures, these results imply that the kagome Heisenberg antiferromagnet has a spin-liquid ground state with a finite gap. The realization and characterization of a kagome Heisenberg antiferromagnet (KHA) with a corner-shared triangle structure ( Fig. 1A) is. Using the power law represented by 1/ ( a + bHα) with α = 0.46, where a and b depend on the fluctuation rate and fluctuating field, we obtain a good fitting to the LF dependence of the muon spin.

Thermodynamics of the spin-half square-kagome lattice antiferromagnet. Over the last decade, the interest in the spin- Heisenberg antiferromagnet (HAF) on the square-kagome (also called shuriken) lattice has been growing as a model system of quantum magnetism with a quantum paramagnetic ground state, flat-band physics near the saturation field.

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.. The quantum spin liquid state was first proposed by physicist Phil Anderson in.

Centred charge donor related diamagnetic susceptibility and optical properties of a spherical GaAs quantum dot are presented. In particular, effects of intrinsic parabolic and shifted parabolic potentials on these quantities are investigated. This is theoretically achieved by solving the Schrödinger equation within the effective mass approximation. It is observed that the parabolic potential.

Best Spin Cycle App. The small spin gap of Mo70V30 can be interpreted to indicate the system in close proximity to the ferrimagnetic phase [13]. In 2009, Todae et al. synthesized W70V30 and measured its magnetic susceptibility [15]. This material was independently synthesized by Li et al., and they also carried out a high-energy Raman scattering experiment [16].

Abstract: Motivated by recent experiments on the quantum-spin-liquid candidate material LiZn2Mo3O8, we study a single-band extended Hubbard model on an anisotropic Kagome lattice with the 1/6 electron filling.
