Half-metallic ferromagnetism with high magnetic moment and high Curie temperature in Co 2 Fe Si

Co 2 Fe Si crystallizes in the ordered L 2 1 structure as proven by x-ray diffraction and Mö β bauer spectroscopy. The magnetic moment of Co 2 Fe Si was measured to be about 6 μ B at 5 K. Magnetic circular dichroism spectra excited by soft x-rays were taken to determine the element-specific magnetic...

Description
Summary:Co 2 Fe Si crystallizes in the ordered L 2 1 structure as proven by x-ray diffraction and Mö β bauer spectroscopy. The magnetic moment of Co 2 Fe Si was measured to be about 6 μ B at 5 K. Magnetic circular dichroism spectra excited by soft x-rays were taken to determine the element-specific magnetic moments of Co and Fe. The Curie temperature was measured with different methods to be ( 1100 ± 20 ) K . Co 2 Fe Si was found to be the Heusler compound as well as the half-metallic ferromagnet with the highest magnetic moment and Curie temperature.
