摘要：

Band-structure calculations in the local spin-density approximation for the vanadium oxide Sb2O2VO3 have been performed to estimate its hopping and exchange parameters. Comparing it with other one-dimensional cuprates and vanadates, we find Sb2O2VO3 to be one of the most ideal inorganic spin-1/2 chain compounds synthesized so far. In connection with the observed spin gap, our results suggest Sb2O2VO3 to be an ideal spin-Peierls compound, with a 25 times smaller exchange interchain coupling and a four times smaller frustration than in CuGeO3.
