Abstract

Magnetization and high-field X-ray powder diffraction measurements were performed for Mn2Sb0.95Ge0.05 with a tetragonal structure in magnetic fields up to 5 T in the 10-300 K temperature range. For B = 0 T and 5 T, a first-order magnetic transition from a ferrimagnetic (FRI) to an antiferromagnetic (AFM) state occurred at Tt ∼ 180 K and 150 K, respectively, and were accompanied by an iso-structural transformation. For this transition from the AFM to FRI state, the lattice parameters a and c changed by |Δa/a| = 0.15% and by |Δc/c| = 0.47% at 180 K. The compound showed both metamagnetic transition from the AFM to FRI state with a hysteresis at the temperature just below Tt and magnetic field-induced iso-structural transformation.
