Half-metallic ferromagnetism with high magnetic moment and high Curie temperature in Co${}_2$FeSi

Sabine Wurmehl, Gerhard H. Fecher, Vadim Ksenofontov +4

Co${}_2$FeSi crystallizes in the ordered L2${}_1$ structure as proved by X-ray diffraction and Mößbauer spectroscopy. The magnetic moment of Co${}_2$FeSi was measured to be about $6{\mu }_B$…
