Abstract
The 51V and 25Mg nuclear magnetic resonance (NMR) spectra have been obtained and magnetic susceptibility has been measured in polycrystalline Mg3V2O8. The analysis of 51V NMR spectra has shown that the line shift, δ(51V) = − 555 ppm, does not depend on temperature. It has been established that vanadium ions V5+ have a zero magnetic moment in this structure. The 25Mg NMR spectrum consists of two lines corresponding to two crystallographically nonequivalent positions of magnesium ions in the Kagome structure: Mg(1) are « spine » and Mg(2) are « cross tie » . Quadrupole frequencies and asymmetry parameters of 25Mg and 51V NMR spectra have been determined. The magnetic susceptibility is turn out to be zero (within the error) and remains constant over at a whole temperature range.
