THE GROUND STATE OF NaV2O5
نویسندگان
چکیده
Neutron and X-ray diffraction experiments have shown that NaV2O5 consists of zig-zag V chains of average valence 4.5 rather than a charge ordered state at room temperature. Both these experiments revealed superlattice reflections below the phase transition temperature TSP < 34 K. The modulation below TSP is due to displacements predominantly of V atoms for which we propose a model. q 1998 Elsevier Science Ltd. All rights reserved

Low-energy excitations in NaV2O5.
In the (ab) polarized Raman scattering spectra of NaV2O5 single crystals, measured with 647.1 nm laser line at T < Tc, we found two modes at 86, and 126 cm not previously reported. These two modes, together with 66, and 106 cm modes, make an array of four low-energy equidistant modes below the energy onset of the continuum at about 132 cm. All four modes are strongly suppressed by increasing Na...
متن کاملAn Electron Spin Resonance Selection Rule for Spin-Gapped Systems
The direct electron spin resonance (ESR) absorption between a singlet ground state and the triplet excited states of spin gap systems is investigated. Such an absorption, which is forbidden by the conservation of the total spin quantum number in isotropic Hamiltonians, is allowed by the Dzyaloshinskii-Moriya interaction. We show a selection rule in the presence of this interaction, using the ex...
متن کامل0 Superexchange in the quarter - filled two - leg ladder system NaV
A theory of superexchange in the mixed valent layer compound NaV2O5 is presented which provides a consistent description of exchange both in the disordered and charge ordered state. Starting from results of band structure calculations for NaV2O5 first an underlying electronic model for a ladder unit in the Trellis lattice is formulated. By using the molecular orbital representation for intra-ru...
متن کاملExistence of a ground state solution for a class of $p$-laplace equations
According to a class of constrained minimization problems, the Schwartz symmetrization process and the compactness lemma of Strauss, we prove that there is a nontrivial ground state solution for a class of $p$-Laplace equations without the Ambrosetti-Rabinowitz condition.
