Introduction. Spin-|$1/2$| kagomé antiferromagnets have played a central role in the study of frustrated magnetism ever since Fazekas and Anderson first proposed a resonating valence bond (RVB) ground state in geometrically frustrated quantum-spin systems [].The kagomé lattice consists of a two-dimensional network of corner-sharing triangles, and it has.

Ground-State Energy and Spin Gap of Spin-1/2 Kagome Heisenberg.

We report a single-crystal D 2 NMR investigation of the nearly ideal spin S = 1 / 2 kagome lattice ZnCu 3 (OD) 6 Cl 2.We successfully identify D 2 NMR signals originating from the nearest neighbors of Cu 2 + defects occupying Zn sites. From the D 2 Knight-shift measurements, we demonstrate that weakly interacting Cu 2 + spins at these defects cause the large Curie. 3=2Crmoments) exhibit spin-glass-like behavior in susceptibility. Quantum effects should play important roles in the magnetism of kagome´ compounds, similar to the case of low dimensional spin systems. A theoretical study of S 1=2 Heisenberg kagome´ systems indicates that the ground state is spin singlet [3]. Ramirez et al. [4] reported.

Observation of Spin-Gap State in Two-Dimensional Spin-1 Kagomé.

. 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).

Numerical diagonalization methods are employed to study spin-1/2 spherical kagome clusters realized in W 72 V 30 and Mo 72 V 30, where the former is expected to have the ideal symmetry I h and the latter is a little distorted. For the ideal model with I h symmetry we calculate spin correlation functions in the ground state, which resemble the spin-1/2 kagome.

Your Publons™ profile is moving to the Web of Science™. From magnetic susceptibility and high-field magnetization measurements, it was found that the ground state is a disordered singlet with the spin gap, as predicted from a recent theory. Exact diagonalization for a 12-site Kagome cluster was performed to analyze the magnetic susceptibility, and individual exchange interactions were evaluated.

Made available by U.S. Department of Energy Office of Scientific and Technical Information. Abstract Numerical diagonalization methods are employed to study spin-1/2 spherical kagome clusters realized in W72V30 and Mo72V30, where the former is expected to have the ideal symmetry Ih and the latter is a little distorted. For the ideal model with Ih symmetry we calculate spin correlation functions in the ground state, which resemble the spin-1/2 kagome.
