Abstract: | The spin-lattice relaxation time T1 of 23Na and 51V nuclei in the quasi-one-dimensional conductor β-Na0.33V2O5 was measured in the temperature region between 77K and the room temperature. The large anisotropy of T1 of 23Na nuclei was observed. The experimental results of T1 of 23Na and 51V nuclei at 77K were analyzed that there exists in β-Na0.33V2O5 the electron hopping motion along site I vanadium chain, of which the correlation time of this hopping motion is about 10?12 sec. |
