(a) Resistivity for (Ca_1-xNa_x)(Zn_2-xMn_x)Sb₂ (x = 0.08, 0.10, 0.12, 0.16, 0.20). (b) The magneto-resistance for (Ca_0.9Na_0.1)(Zn_1.9Mn_0.1)Sb₂ under the applied external magnetic fields of 0 T, 3 T, 5 T, 9 T. (c) The field dependence of MR for (Ca_0.9Na_0.1)(Zn_1.9Mn_0.1)Sb₂ from −9 T to 9 T at 2 K. The MR is defined as [ρH−ρ0]/ρ0 .
