摘要：

We have conducted high pressure V-51 NMR experiments to investigate the local magnetic properties of a quasi-one-dimensional superconductor beta-Na0.33V2O5. The experimental results of the V-51 Knight shift and the nuclear spin-lattice relaxation rate indicate that the pressurizing suppresses the static and dynamical magnetic susceptibilities in the metallic phase. An enhancement of the antiferromagnetic spin fluctuations appears at the V2 site with increasing pressure. (C) 2009 Elsevier B.V. All rights reserved.
