Abstract: Co2FeSi crystallizes in the ordered L2(1) structure as proven by x-ray diffraction and Mo beta bauer spectroscopy. The magnetic moment of Co2FeSi was measured to be about 6 mu(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. Co2FeSi was found to be the Heusler compound as well as the half-metallic ferromagnet with the highest magnetic moment and Curie temperature. (C) 2006 American Institute of Physics.
