摘要：

We consider spin vacancies as well as spin-one impurities in RVB states. In the flux phase a spin vacancy site induces a bound state with a free spin. The spin distribution and the local Khight shift in the vicinity of the vacancy is calculated as well as the interaction potential between two vacancies. When a spin-one impurity is considered, its low energy properties can be described in terms of an underscreened Kondo problem. These findings may be of relevance for Zn and Ni impurities in underdoped HTSC materials.
