We review electron spin resonance (ESR) experiments in several concentrated Yb-, Ce-, and Eu-based intermetallic systems. Recent theoretical studies attribute well resolved ESR signals with hybridization effects between 4f and conduction electrons (CE) in the presence of ferromagnetic (FM) fluctuations. We believe that the ESR absorption is caused here by a novel type of ESR excitations – hybridized electronic states, which are created in some strongly correlated electronic systems due to hybridization between the 4f-orbitals and the wavefunctions of the CE of the outer d, s, and p shells in conjunction with FM RKKY interaction.
