Abstract

Heusler compounds are fascinating alloys that present a plethora of physical phenomena. They have been used for various applications, including spintronics, and their functional properties are quite sensitive to their structural order. The authors undertake a theoretical and experimental study of the effects of Cr doping on the structural, magnetic, transport, and electronic properties of Co₂FeSi alloys. The improved understanding of the interplay of intrinsic defects that they attain should help to enhance the performance of devices based on this class of materials.
