GdSb and TmSb are typical 'model' materials in rare earth compounds. The former is an exchange interaction only sample and the latter is a CEF only sample. In order to compare the transport properties between the two samples, we have measured the Hall effect and resistivity of pure GdSb and TmSb in various fields. The CEF effect and magnetic scattering have been observed in both resistivity and Hall effect measurements for TmSb and GdSb, respectively. The mobilities of electrons and holes as well as the carrier concentration are calculated using the experimental data.
