Abstract
Large scale production of single crystalline phase of Heusler Co2FeSi alloy microwire is reported. The long microwire (â¼1â¯km) with the metallic nucleus diameter of about 2â¯Âµm is characterized by well oriented monocrystalline structure (B2 phase, with the lattice parameter aâ¯=â¯5.615â¯Ã
). Moreover, the crystallographic direction [1 0 1] is parallel to the wire's axis along the entire length. Additionally, the wire is characterized by exhibiting a high Curie temperature (Tcâ¯>â¯800â¯K) and well-defined magnetic anisotropy mainly governed by shape. Electrical resistivity measurement reveals the exponential suppression of the electron-magnon scattering which provides strong evidence on the half-metallic behaviour of this material in the low temperature range.
