Half-Metallic Ferromagnetism in the Heusler Compound Co${}_2$FeSi revealed by Resistivity, Magnetoresistance, and Anomalous Hall Effect measurements

Dirk Bombor, Christian G. F. Blum, Oleg Volkonskiy +4

We present electrical transport data for single-crystalline Co${}_2$FeSi which provide clear-cut evidence that this Heusler compound is truly a half-metallic ferromagnet, i.e. it pos…
