Spin dynamic properties of the Kondo system

Abstract

The Kondo effect in the dynamics of localized moments (LM) in metallic host is studied in the whole temperature range, taking into account the electron bottleneck effect. Calculations of the total dynamic response of the Kondo system are performed within the approximation that the magnetic moment of the impurity is not quenched by conduction electrons (CE). Electron spin resonance (ESR) parameters are studied for different conditions of the dynamic coupling between LM and CE. Experimental ESR studies of the Kondo system Au:Yb are discussed. © 1992.
