Abstract
Co2FeSi crystallizes in the ordered L21 structure as proved by X-ray diffraction and Mößbauer spectroscopy. The magnetic moment of Co2FeSi was measured to be about 6μB at 5K. Magnetic circular dichroism spectra excited by soft X-rays (XMCD) were taken to determine the element specific magnetic moments of Co and Fe. The Curie temperature was measured with different methods to be (110020)K. Co2FeSi was found to be the Heusler compound as well as the half-metallic ferromagnet with the highest magnetic moment and Curie temperature.
