Experimental and Theoretical Investigation of Polycrystalline Hexagonal Mn2FeSn compound
Original language description
The recently discovered hexagonal structure of the Mn₂FeSn alloy significantly influences its physical properties, making them markedly different from those of the cubic Mn₂FeSi and Mn₂FeAl systems. This study focuses on both theoretical and experimental investigations of bulk Mn₂FeSn, examining the relationship between its structure, open-volume defects, and mechanical and magnetic properties. Induction-melted Mn₂FeSn ingots, homogenized at 773 K for 100 hours under an argon atmosphere and slowly cooled to room temperature, were selected for analysis. The stoichiometry of the prepared alloys was independently verified using surface-sensitive energy-dispersive X-ray spectroscopy and bulk-sensitive neutron activation analysis. All samples, in both as-cast and annealed states, exhibited a three-phase composition dominated by a Ni₃Sn-type hexagonal structure. Various experimental techniques – including positron annihilation spectroscopy, hardness and instrumented indentation testing, and low-temperature magnetic measurements – were employed to characterize the physical properties of the samples. These results were further supported by density functional theory (DFT) calculations. The annealed Mn₂FeSn sample revealed a Mn vacancy concentration of approximately 70 ppm, a Young’s modulus of about 100 GPa, and a pronounced exchange bias effect, with a maximum value of -340 kA/m at 5 K.
