ESR study on the excited state energy spectrum of SrCu(BO) -a central role of multiple-triplet bound states
H. Nojiri, H. Kageyama, Y. Ueda +1
The excited state energy spectrum of a two-dimensional dimer system SrCu(BO) has been investigated by high field ESR. Various types of multiple-triplet bound states-exc…
Charge ordering signatures in the optical properties of beta-Na0.33V2O5
C. Presura, M. Popinciuc, P. H. M. van Loosdrecht +4
Temperature dependent optical spectra are reported for beta-Na0.33V2O5. The sodium ordering transition at T_Na = 240 K, and in particular the charge ordering transition at T_MI = 1…
Magnetic Superstructure in the Two-Dimensional Quantum Antiferromagnet SrCu2(BO3)2
K. Kodama, M. Takigawa, M. Horvatic +6
We report the observation of magnetic superstructure in a magnetization plateau state of SrCu2(BO3)2, a frustrated quasi-two-dimensional quantum spin system. The Cu and B nuclear m…
Orbital Dimerization and Dynamic Jahn-Teller Effect in NaTiSiO
M. J. Konstantinović, J. van den Brink, Z. V. Popović +3
We study with the Raman scattering technique two types of phase transitions in the pyroxene compounds NaMSiO (with M=Ti, V, and Cr). In the quasi one-dimensional S=1/2 syst…
