Abstract

The magnetic properties of ferrimagnetic Mn_1.9Fe_0.1Sb_0.9Sn_0.1 with a Cu ₂Sb-type tetragonal structure were investigated in the temperature range 10 to 360 K and in magnetic fields up to 5 T. The lattice parameters a and c were estimated to be 0.407 and 0.655 nm, respectively, at 293 K. The saturation magnetization at 10 K was 39.1 A m²/kg (1.62 μ_B per formula unit), which was slightly smaller than the value at 75 K, and the magnetization showed thermal hysteresis between 70 and 230 K. The compound showed a first-order magnetic transition from the ferrimagnetic to a paramagnetic-like state with a thermal hysteresis in the vicinity of 320 K. The results are discussed on the basis of the ferrimagnetic and antiferromagnetic transitions and spin reorientation.
