摘要

The RNiSb compounds (R chemical bounds Ho, Er, Tm, Yb and Y) and some selected solid solution members such as (Zr_(1-x) Er_x)Ni(Sn_(1-x)Sb_x) and ErNiSb_(1-x)Pn_x (Pn chemical bounds As, Sb, Bi) have been studied. They all crystallize the MGAgAs structure type, which can be considered as a naCl structure type in which half of the interstitial tetrahedral sites are occupied by Ni atoms. The measured values of the Seebeck coefficients, at room temperature, are positive for RNiSb (R chemical bounds Ho, Er, Yb and Y) compounds and ErNiSb_(1-x)Pn_x (Pn chemical bounds As, Sb, Bi) solid slid solutions, but for (Zr_(1-x)Er_x)Ni(Sn_(1-x)Sb_x) members vary from negative to positive values when 0
