Approaching the QCP from the disordered phase we study the spatial distribution of spin density and staggered magnetization induced by the impurity. Using two methods (self-consistent Born approximation and renormalization group) we found a power law decay of the spin density $\\propto 1/r^3$, and of the staggered magnetization $\\propto 1/r$ with relevant logarithmic corrections.
