Abstract

The effect of substitution of Co for Fe on structure, magnetic, and electrical resistivity of Heusler-type Fe3−x Co x Si (0 ≤ x ≤ 1) alloys was investigated using X-ray powder diffraction, 57Fe Mössbauer spectroscopy, magnetic, and electrical transport measurements. The results revealed that these alloys consist of ordered DO3 phase and some L21 phase up to x ≤ 0.5. However, for x > 0.5, the alloys consisted of L21 ordered phase and B2 disordered phase. The magnetization value was close to that predicted from Slater-Pauling rule for x ≥ 0.5 alloys. The Curie temperature increased from 832 K (559 °C) for x = 0 (Fe3Si) alloy to 1016 K (743 °C) for x = 1 (Fe2CoSi) alloy. Electrical transport studies revealed the presence of half-metallic behavior at low temperatures in x ≥ 0.5 alloys. No half-metallic behavior was observed for x = 0 and 0.25 alloys; however, a high resistivity with ferromagnetism was observed in these alloys, which is desirable for ferromagnetic metal/semiconductor spintronic devices.
