Charge and magnetic ordering in GaV2O5 and the new lacunar spinel oxide GaV4O8.
Vanadium oxides have been intriguing substances in solid state physics due to their behavior as strongly correlated electron systems. We have discover a new mixed valent vanadium oxide (GaV4O8) with a lacunar spinel structure. We have also prepared the non-studied mixed valent GaV2O5. Neutron diffraction is needed in order to elucidate their magnetic structures and possible low temperature charge ordering transitions.
