Chain Formation by Spin Pentamers in eta-Na9V14O35
D. V. Zakharov, H. -A. Krug von Nidda, J. Deisenhofer +4
The nature of the gapped ground state in the quasi-one-dimensional compound eta-Na9V14O35 cannot easily be understood, if one takes into account the odd number of spins on each str…
Unconventional anisotropic superexchange in NaV2O5
M. V. Eremin, D. V. Zakharov, R. M. Eremina +5
The strong line broadening observed in electron spin resonance on NaVO is found to originate from an unusual type of the symmetric anisotropic exchange interaction with sim…
Structural precursor to the metal-insulator transition in V_2O_3
P. Pfalzer, G. Obermeier, M. Klemm +2
The temperature dependence of the local structure of V_2O_3 in the vicinity of the metal to insulator transition (MIT) has been investigated using hard X-ray absorption spectroscop…
Surface acoustic wave investigations of the metal-to-insulator transition of V2O3 thin films on lithium niobate
C. Mueller, A. A. Nateprov, G. Obermeier +4
Thin V2O3 films were deposited on a piezoelectric substrate by electron-beam evaporation. Surface acoustic waves (SAW) were generated by interdigital-transducers (IDTs). The attenu…
