Magneto-Structural Properties of Co2FeIn Heusler Nanowires for Spintronics Applications

$\text{Co}_{2}\text{FeIn}$
Heusler alloy nanowires were synthesized through a pulsed electrodeposition process in the pores of alumina membranes. SEM and TEM analysis of nanowires display a diameter of around

. SAED analysis and X-ray diffraction patterns indicate the presence of a cubic L21 crystalline phase. VSM magnetic hysteresis loops of the as-synthesized nanowires array evidenced an easy magnetization axis lying along the nanowires length and showing a coercivity of around 70 Oe, which is of the same order than the switching field values measured in single isolated nanowires by NanoMOKE. FORC analysis revealed also high magnetostatic interaction among the

nanowires in the array, but with low coercive field distribution.
