摘要：

The quasi-one-dimensional hollandite vanadate K2V8O16 is believed to have a spin-singlet-like transition at approximate to 170 K. We investigated a polycrystalline sample of K2V8O16 using zero-field mu SR. Paramagnetic electronic fluctuations, manifested as a relaxation of the muon polarization function, exist at all temperatures. There are only smooth and slight changes in the relaxation rate as the temperature of the sample is decreased from 200 K. Below about 10 K, there is a significant increase in the relaxation rate, implying a slow-down of the paramagnetic fluctuations.
