Abstract

Magnetization and electrical resistivity measurements were carried out for polycrystalline Mn₂Sb_1-xGe_x (0.05 ≤ x ≤ 0.2) in magnetic fields up to 16 T in the 4.2 - 600 K temperature range in order to investigate the magnetic and the electrical properties under high magnetic fields. Mn₂Sb_0.92Ge_0.08 showed a Curie temperature, T _C, of 532 K and a first order magnetic transition from a ferrimagnetic (FRI) to an antiferromagnetic (AFM) phase at T _t = 230 K with decreasing temperature in a zero magnetic field. With increasing x, T _C decreased and T _t increased. For Mn₂Sb_0.92Ge_0.08, a matamagnetic transition from an AFM to a FRI phase was observed at 215 K. The magnetic phase diagram of Mn₂Sb_1-xGe_x is presented.
