Magnetization measurements on “as prepared” and annealed Fe3-xMnxSi alloys

Abstract EN

The magnetic properties of the alloy system Fe3-xMnxSi have been studied by measuring magnetization for samples with x = 0, 0.1, 0.25, 0.5, and by thermal scanning techniques for samples with x = 0, 0.1.

The results reveal that the system is ferromagnetic in this composition range.

Zero field cooling and field cooling magnetization measurements indicate a similar magnetic ordering and magnetic anisotropy in all samples.

The saturation magnetization for the annealed samples was higher than that for “as prepared” samples.

This is attributed to the reduction of magnetic domain boundaries rather than to improving magnetic order as a result of annealing.

Further, TC values determined from thermal DSC measurements are in good agreement with previously reported results based on magnetic measurements.
