Nuclear Magnetic Resonance of "V has been investigated in both the antiferro-magnetic and the paramagnetic states of V.0.. Two signals associated withmagnetic V"(3d') sites have hyperfine fields (ff.0of - 199.8 and -208.7(.50.3)k0e at 1.25 K which are dominated by intra-ionic dipolar field. The temperaturedependence of H. was well described by an equation H,q=H..(] -AT') with{=(I6.0fO.5)x]0 '(K ')in the range 1.32<7'<2.22 (K). Tlu'ee signals fromV" sites were also observed. Magnetic suscepti bility at high and low field behavesdifferently below the N<Set temperature of 5 K. These results together with theconvex curve of magnetization versus field in the paramagnetic state are discussedin terms of the insulating low-dimensional magnetic system with small anisotropyenergy and predominant ferromagnetic interaction along linear chains.
