Observation of Spin Freezing in CaV 4 O 9 and CaV 2 O 5 by μ SR

چکیده
We have performed muon spin relaxation and susceptibility measurements of CaV4O9 and CaV2O5, systems in which spin gap-like behavior has been found. We observe spin freezing in the two compounds below 12 K and 50 K, respectively. Our results indicate the possibility that a substantial fraction of the vanadium magnetic moment is not in a spin singlet state at low temperatures in either material. 75.50.Lk, 76.75.+i Typeset using REVTEX

Raman Scattering from Magnetic Excitations in the Spin Ladder Compounds CaV 2 O 5 and MgV
We present the Raman scattering spectra of CaV 2 O 5 and MgV 2 O 5. Our analysis of the magnetic modes shows that the magnetic ordering in CaV 2 O 5 can be described using two-leg ladder Heisenberg antiferromagnetic model with J /J ⊥ ∼ 0.1, and a small interladder exchange. The spin-gap and exchange constant are estimated to be ∆ s ∼ 400 cm −1 (570 K) and J ⊥ ∼ 640 K. No magnon bound states are...

We study the stability of the 4-site plaquette order in a model recently introduced by Katoh and Imada to explain the spin gap observed in CaV4O9. We show that all relevant types of order (4-site plaquette, dimerized, Néel) can be described within the framework of Schwinger boson mean field theory, and we make predictions regarding their relative stability. The results are compared to exact dia...

We examined a two-dimensional Heisenberg model with two kinds of exchange energies, Je and Jc. This model describes localized spins at vanadium ions in a layer of CaV4O9, for which a spin gap is found by a recent experiment. Comparing the high temperature expansion of the magnetic susceptibility to experimental data, we determined the exchange energies as Je ≃ 610 K and Jc ≃ 150 K. By the numer...
متن کاملExact Ground and Excited States of Frustrated Antiferromagnets on the Cav 4 O 9 Lattice
The experimental observation of a spin-gap in the antiferromagnetic spin2 compound CaV4O9 has been attributed to the formation of a plaquette resonating-valence-bond (PRVB) state in the underlying 1/5-depleted square lattice. We construct a spin2 model on the 1/5-depleted lattice for which the PRVB state can be shown to be the exact ground state in a particular parameter regime. In a subspace o...

In the title coordination polymer, {[Sr(C(4)HO(4))(2)(H(2)O)(5)]·0.5H(2)O}(n), the Sr(2+) ion is coordinated by three monodentate hydrogensquarate (hsq) anions and six aqua ligands in a distorted SrO(9) monocapped square-anti-prismatic geometry. The hsq anions and water mol-ecules bridge the metal ions into infinite sheets lying parallel to (100). The O atom of the uncoordinated water mol-ecule...
