  • Crystal electric field parameters for Yb 3+ ion in YbRh 2Si 2 
    Kutuzov A.; Skvortsova A. (2011)
    The tetragonal crystal electric field parameters for Yb 3+ ion in YbRh 2Si 2 are determined from the analysis of the literature data on angle-resolved photoemission, inelastic neutron scattering and electron paramagnetic ...

    Belov S.; Kutuzov A.; Kochelaev B.; Sichelschmidt J. (2012)
    A model of spin relaxation of Kondo lattices is proposed to explain the angular dependence of the electron spin resonance (ESR) parameters in the heavy fermion compounds Y bIr 2Si 2 and Y bRh 2Si 2. A perturbational scaling ...

    Sichelschmidt J.; Kambe T.; Fazlishanov I.; Zakharov D.; Krug von Nidda H.; Wykhoff J.; Skvortsova A.; Belov S.; Kutuzov A.; Kochelaev B.; Pashchenko V.; Lang M.; Krellner C.; Geibel C.; Steglich F. (2010)
    We present the field and temperature behavior of the narrow electron spin resonance (ESR) response in YbRh2Si2 well below the single ion Kondo temperature. The ESR g-factor reflects a Kondo-like field and temperature ...

    We consider the local properties of the Yb3+ ion in the crystal electric field in the Kondo lattice compounds YbRh2Si2 and YbIr2Si2. On this basis we have calculated the magnetic susceptibility, taking into account the ...

  • Why could electron spin resonance be observed in a heavy fermion Kondo lattice? 
    Kochelaev B.; Belov S.; Skvortsova A.; Kutuzov A.; Sichelschmidt J.; Wykhoff J.; Geibel C.; Steglich F. (2009)
    We develop a theoretical basis for understanding the spin relaxation processes in Kondo lattice systems with heavy fermions as experimentally observed by electron spin resonance (ESR). The Kondo effect leads to a common ...
