The interest in studies of heavy fermion (HF) com
pounds based on uranium, cerium, ytterbium, and
other 4f and 5f elements has significantly increased
recently. The magnetic properties, unique in many
cases, of such concentrated Kondo systems are deter
mined by the competition of several interactions of
different natures (crystalline electric field (CEF),
indirect interspin RKKY interaction, hybridization
between f orbitals and the band states, screening of the
localized magnetic f moments due to the Kondo
effect, etc.) [1]. Using the electron spin resonance
(ESR) technique to study these compounds is usually
impossible without the introduction of additional
paramagnetic probes (as a rule, rear earth ions with a
concentration of less than 2%), due to very intense
spin lattice relaxation of the f ions and the resulting
