Abstract

The susceptibility (χ) and μSR measurements of pure and diluted CVO were reported and some exotic fetures of their ground states were discussed. As such, a signature of slowing down of spin fluctuations with decreasing temperature, followed by slow and nearly temperature-independent spin fluctuations between T=1.0 and 50 mK in the S=1/2 kagome spin system CVO was found. These fluctuations exhibit quantum character, and persist at T=50 mK without any signature of long-range or static spin order.
