Spin-1/2 spherical kagom#233; 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.

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. In this paper, we use microcanonical thermal pure quantum mTPQ.

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

Apr 10, 2008 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. For the spherical kagome system W72V30, which is a magnetic cluster with 30 V4 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. In this paper, we use microcanonical thermal pure quantum mTPQ states to calculate the temperature dependence of. 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.

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

For the ideal quantum spin icosidodecahedron with next-nearest neighbor interactions, we find that there exist many singlet states before the first triplet state, which is an evidence of the resonating valence bond RVB state, and the experimental susceptibilities of Mo72V30 measured by Muller et al. and Botar et al. cannot be reproduced.

Evidence of low-energy singlet excited states in the spin-1/2.

It had been believed that Mo 72 V 30 could be described by the I h model, and a quantum Monte Carlo calculation of the magnetic susceptibility was performed in order to extract the exchange. Made available by U.S. Department of Energy Office of Scientific and Technical Information. The high-temperature susceptibility was reproduced by the I h model with J = 245 K, but the low-temperature part was not.33 As the temperature decreases, the calculated suscep-tibility of the I h model vanishes much faster than the experi-mental susceptibility. In particular, the experimental spin gap.
