INVERSE-HEUSLER Mn2FeSi ALLOY PREPARED BY POWDER METALLURGY ROUTE

Popis výsledku v původním jazyce

The Mn2FeSi inverse-Heusler alloy was prepared by solid-state reactions using ball milling for 168 h in n-hexane. Two milling procedures varying in the ball-to-powder ratio, namely 4:1 and 10:1, were used to follow their influence on alloy formation and its physical properties. In both cases no Heusler structure was obtained directly and therefore the subsequent annealing at 1223 K for 1.5 h in pure Ar was applied. The energy-dispersive X-ray analysis resulted in the chemical composition about (49.0-49.9) at.% Mn, (25.3-25.6) at.% Fe, and (24.8-25.4) at.% Si, in a good agreement with nominal one. X-ray diffraction of both powders confirmed inverse-Heusler XA structure of lattice parameters 0.5675 nm (4:1) and 0.5677 nm (10:1), only slightly higher as theoretically obtained 0.560 nm. The presence of minor oxidation phases was also observed in the particle structure of powders. Magnetic properties were analyzed at low and room temperatures. Both alloys exhibit paramagnetic behavior at room temperature confirmed by transmission Mössbauer spectroscopy measurements. Different magnetic behavior of alloys is observed below 65 K.
