Abstract
The polarization of the electron cloud around a magnetic impurity in a dilute magnetic alloy has been considered in the low-temperature region where perturbation theory is not applicable. It is found that the electron-spin-impurity-spin correlation function shows an exponentially damped negative oscillation instead of Ruderman-Kittel-Kasuya-Yosida-type oscillation. The range of the Kondo spin-compensated state is calculated to be , where is the conduction bandwidth, is the Fermi momentum, and is the energy corresponding to the Kondo temperature .
