Communication--Electrodeposition, Microstructure and Magnetic Properties of Co2FeSn Heusler Alloy Nanowires.

Co₂FeSn Heusler alloy nanowires with the diameters of 30 nm and 60 nm were firstly prepared by direct current electrodeposition. Magnetic measurements revealed the excellent soft ferromagnetism of Co₂FeSn nanowires. The easy magnetization axis is perpendicular to the long axis of nanowires and the magnetic reversal of Co₂FeSn nanowires occurs via coherent rotation model. In addition, the influence of the wire diameter on the magnetic properties of Co₂FeSn nanowires was discussed. Co₂FeSn Heusler alloy nanowires synthesized in this work shows tunable magnetic properties and are of potential interest for magnetic device and spintronic applications. [ABSTRACT FROM AUTHOR]
