Magnetic susceptibility of CdSb doped with Mn,Fe, Ni and La

This paper is devoted to the study of the temperature dependence of the magnetic susceptibility of CdSb doped with Mn, Fe, Ni and La. Analyzing the measured curves on the assumption that the impurities are substitutional and using the Hall constant measurements, we were able to determine the magnetic moments of Fe and Ni impurities and to obtain some information concerning the bond of these atoms with their nearest neighbours. The impurities Mn and La are dissolved in CdSb only partly as substitutional impurities, the major part most probably forming with antimony a new phase which is strongly paramagnetic and fully overgrows the diamagnetism of the parent semiconductor compound.
