Abstract: Electron spin resonance (ESR) and magnetic-susceptibility experiments in the rare-earth-doped (R = Nd, Er, and Yb) cubic semiconducting YBiPt allow estimates of the fourth (A(4)) and sixth (A(6)) order crystal-field parameters for this compound. It is found that these parameters are of the same order for all the R studied. On the other hand, no crystal-field effects were found for the Gd3+ doped single-crystal system. Consistent with the small gap semiconducting character of the YBiPt intermetallic compound, a Dysonian ESR line shape with no g shift and Korringa broadening was observed. [S0163-1829(99)10925-1].
