Optical properties and electronic structure of Ca-doped alpha'-NaV2O5
C. Presura, D. van der Marel, M. Dischner +2
The dielectric function of alpha'-Na(1-x)Ca(x)V2O5 (0 < x < 20%) was measured for the a and b axes in the photon energy range 0.8-4.5 eV at room temperature. By varying the Ca-conc…

CuSiO_3 : a quasi - one - dimensional S=1/2 antiferromagnetic chain system
M. Baenitz, C. Geibel, M. Dischner +5
CuSiO_3, isotypic to the spin - Peierls compound CuGeO_3, was discovered recently as a metastable decomposition product of the silicate mineral dioptase, Cu_6Si_6O_{18}\cdot6H_2O.…

Electron spin resonance study of Na_{1-x}Li_xV_2O_5
M. Lohmann, H. -A. Krug von Nidda, A. Loidl +3
We measured X-band electron-spin resonance of single crystalline sodium vanadate doped with lithium, Na_{1-x}Li_xV_2O_5 for 0 < x < 1.3% . The phase transition into a dimerized pha…
