Abstract:

The magnetic susceptibility and the electron spin resonance in the X-band of the transition metal oxide compound MgVO3 are reported. We show that this compound, made of weakly coupled infinite chains of VO5 pyramids, behaves as a S =1/2 one-dimensional Heisenberg antiferromagnet. From the ESR and magnetic experiments we deduce the Néel temperature K, the in-chain coupling constant K and the g-factor values g x = g z =1.972(2), g y =1.946(1) for V4+ ions in MgVO3.
