Multiferroic FeTeOBr: Alternating spin chains with frustrated interchain interactions
M. Pregelj, H. O. Jeschke, H. Feldner +11
A combination of density functional theory calculations, many-body model considerations, magnetization and electron spin resonance measurements shows that the multiferroic FeTe…
The antiferromagnetic/paramagnetic transition in mixed-spin compounds R2BaNiO5
J. V. Alvarez, Roser Valenti
We present an extensive Quantum Monte Carlo study of the magnetic properties of the mixed-spin quantum systems R2BaNiO5 (R= magnetic rare earth) which show coexistence of 3-dimensi…
Low Energy Singlets in the Excitation Spectrum of the Spin Tetrahedra System Cu_2Te_2O_5Br_2
P. Lemmens, K. Y. Choi, A. Ionescu +8
Low energy Raman scattering of the s=1/2 spin tetrahedra system Cu_2Te_2O_5Br_2 is dominated by an excitation at 18 cm^{-1} corresponding to an energy E_S=0.6Δ, with Δthe spin gap…
Evidence for an unconventional magnetic instability in the spin-tetrahedra system Cu_2Te_2O_5Br_2
P. Lemmens, K. -Y. Choi, E. E. Kaul +8
Thermodynamic experiments as well as Raman scattering have been used to study the magnetic instabilities in the spin-tetrahedra systems Cu_2Te_2O_5X_2, X=Cl and Br. While the phase…
