An approach related to the bottleneck effect is proposed for an origin of the electron spin resonance (ESR) of a Kondo ion (Yb3+) in the undoped Kondo-lattice systems YbRh2Si2 and YbIr2Si2. The effects observed for the ...
We theoretically investigated the static magnetic susceptibility in the heavy fermion compounds YbRh2Si2and YbIr2Si2. The molecular field approximation together with the renormalization of the Kondo interaction by the high ...
We investigated the spin dynamics in the heavy fermion compounds YbRh2Si2and YbIr2Si2. The contributions of the resonant and nonresonant parts of the total transverse magnetization to the electron spin resonance (ESR) ...
