Abstract

We report the more recent advances in electron spin resonance (ESR) of few undoped Yb-based intermetallic compounds with heavy fermions (HF). The X-band ESR spectra of the Kondo lattices YbBiPt, YbRh2Pb, and YbT2Zn20 (T = Fe, Co) are presented. A comparison with earlier ESR studies in YbRh2Si2 and YbIr2Si2 shows that the exchange interactions between the Yb 4f electrons and relevant conduction electron (cl, s-, or p-like) bands as well as the hybridization crystalline electric field (CEF) effects should be taken into account in order to develop a reliable model of spin dynamics in the Yb-based HF systems.
