摘要: Abstract The transverse susceptibility if magnetic systems described by the Anderson model is calculated evaluating self energy for two particle Green function. results are applied to semiconductors and metals. In first case a shift in resonance frequency obtained as well continuum of excitations corresponding promotion electrons from localized state conduction band states. metallic Korringa relation relaxation time limit obtained. real imaginary parts given functions distance level Fermi level.
