Tokyo University of Science Theoretical study on spin-1/2 antiferromagnetic kagome systems with a spin gap Principal Investigator Principal Investigator FUKUMOTO Yoshiyuki Project Period (FY) 2011 - 2013 Research Category Grant-in-Aid for Scientific Research (C) Research Field Condensed matter physics II Research Institution. To explain the spin susceptibility data, we will have to argue that the background subtraction in Fig. 2 is such that the susceptibility has dropped to a small value below the first-order transition at 200 K; this means that the spin gap and the exchange scale J are above 200 K. This argument will allow us to get around the issue of the absence.

Magnetic susceptibility analysis reveals that, whereas Mo72V30 contains some degree of structural distortion that decreases its spin gap, the structure of W72V30 can be described as a regular (non-distorted) icosidodecahedron.

Kagome lattice antiferromagnets and Dzyaloshinsky-Moriya.

Apr 01, 2010 · The entropy properties of the antiferromagnetic spin-1 ∕ 2 Ising model in the presence of the external magnetic field on the kagome lattice are studied in the framework of various effective-field theory cluster approximations up to the size of the cluster consisting of 12 connected sites, which form typical basic star-like geometrical. 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 pr. Skip to Main Content. Canonical-Ensemble Calculations of the Magnetic Susceptibility for a Spin-1/2 Spherical Kagome Cluster With Dzyaloshinskii–Moriya Interactions by Using Microcanonical Thermal. Here we consider the spin axis dynamics of Kepler-62f and Kepler-186f, both of which reside in the habitable zone around their host stars. Using N-body simulations and secular numerical integrations, we describe their obliquity evolution for particular realizations of the planetary systems.... Starting from a discrete spherical [Mo(132.

A two-dimensional spin liquid in quantum kagome ice - Nature.

Aug 03, 2007 · Stuck in the middle with you: The spherical cluster {(Mo)Mo 5} 12 Cr 30 (1) fills, with its spin, a gap in the series of the analogous Fe (S=5/2) and V (S=1/2) clusters. This allows a deeper understanding of the magnetic properties of the series members, particularly with reference to geometric frustration, also found in the famous Kagomé lattices.

Gapless spin liquid behavior in a kagome Heisenberg.

Have demonstrated unique low-energy excitations of the spherical kagomé networks and their sensitivity to the cluster symmetry. DOI: 10.1103/PhysRevB.99.064430 I. INTRODUCTION In geometrically frustrated spin systems, conventional long-range orderings are prevented because of the enormous degeneracy of the ground state. In such cases, nontrivial.

Dimer-dimer Correlations and Magnetothermodynamics of S=1/2.

We provide strong numerical evidence, using improved variational wave functions, for a ground state with vanishing spin gap in the spin-$1/2$ quantum Heisenberg model on the kagome lattice. Abstract. 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 Lan.

Canonical-Ensemble Calculations of the Magnetic Susceptibility.

Sep 09, 2005 · The syntheses and magnetic susceptibilities of a pure series of rare copper minerals from the atacamite family with general formula ZnxCu4-x(OH)6Cl2 (0 ≤ x ≤ 1) are reported. The structure of these compounds features a corner-sharing triangular kagomé lattice of antiferromagnetically coupled Cu(II) ions. We correlate the onset of magnetic ordering with the mole fraction of paramagnetic Cu. Spin Gap And Susceptibility Of Spherical Kagome Cluster Mo72V30. Previous. Sun slots.

Extending the {(Mo)Mo5}12M30 Capsule Keplerate Sequence... - ResearchGate.

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. To clarify why the experimental magnetization curve of the spherical kagomé cluster in {W 72 V 30} at 0.5 K shows no sign of.

Extending the {(Mo)Mo5}12M30 Capsule Keplerate Sequence: A.

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]. In general, there are four ways to execute a spin-off: Regular spin-off - Completed all at once in a 100% distribution to shareholders. Majority spin-off - Parent retains a minority interest (< 20%) in SpinCo and distributes the majority of the SpinCo stock to shareholders. Equity carve out (IPO) / spin-off - Implemented as a second step.

We report an approach of exploring the interaction between cationic surfactants and a type of structurally well-defined, spherical "Keplerate" polyoxometalate (POM) macroanionic molecular clusters, {Mo72V30}, in aqueous solution. The effectiveness of the interaction can be determined by monitoring the size change of the "blackberry.
