Mn_{2}Sb_{0.95}Ge_{0.05} and Mn_{2}Sb_{0.9}Sn_{0.1} showed a first-order magnetic transition from a ferrimagnetic (FRI) to an antiferromagnetic (AFM) phase in the vicinity of T_{t} = 172 K and 190 K, respectively, with decreasing temperature in a zero magnetic field. With increasing x, T_{C} decreased slightly and T_{t} increased. The electrical resistivity changes abruptly by 87% for Mn_{2}Sb_{0.95}Ge_{0.05} and 43% for Mn_{2}Sb_{0.9}Sn_{0.1} at T_{t}. The magnetic phase diagrams of Mn_{2}Sb_{1-x}Ge_{x} and Mn_{2}Sb_{1-x}Sn_{x} are presented.}, pages = {37--42}, title = {Magnetic properties of Mn_{2}Sb_{1-x}Z_{x} (Z = Ge, Sn)}, volume = {46}, year = {2013} }
