Abstract

The single-phased Co2MnSi Heusler alloy has been successfully prepared by the combustion synthesis (CS) method using a homogeneous (2Co + Mn + Si) blend of elemental powders. X-ray diffraction and SEM results showed that the average grain sizes of Co2MnSi Heusler alloy are to be in the range of 20 to 35 µm. The specific saturation magnetization of Co2MnSi Heusler alloys obtained by combustion synthesis achieved a maximum value of 130 emu/g. It was also observed that the synthesized alloy has an electrical resistivity of 0.37 µOhm·m, a Seebeck coefficient of − 17.9 µV/K, and thermoelectric power of 1170 µW/m/K2.
