In this work the basic strategies for the preparation of Co 2 Mn 0.5 Fe 0.5 Si as an example for Heusler alloy thin films will be described. Texture and magnetic properties of these films will be discussed, especially with regard to different buffer layers and annealing temperatures. Finally, we will show the integration of Heusler thin films into magnetic tunnel junctions (MTJs) and calculate the effective spin polarization. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
