Specific Heat of the S=1/2 Two-Dimensional Shastry-Sutherland Antiferromagnet SrCu2(BO3)2 in High Magnetic Fields
H. Tsujii, R. C. Rotundu, B. Andraka +3
We characterize the field-induced magnetic phases of SrCu2(BO3)2, a frustrated spin-1/2 Heisenberg antiferromagnet in the two-dimensional Shastry-Sutherland lattice, using specific…
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…
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…
Magnetic Susceptibilities of Spin-1/2 Antiferromagnetic Heisenberg Ladders and Applications to Ladder Oxide Compounds
D. C. Johnston, M. Troyer, S. Miyahara +11
A comprehensive theoretical and experimental study is presented of the magnetic susceptibility versus temperature χ(T) of spin S = 1/2 two- and three-leg Heisenberg ladders and lad…
