Heusler alloys have attracted huge interest due to their outstanding magnetic properties which make them suitable for various applications. Bulk Heusler alloys are applied in magnetic shape memory and magneto-caloric devices. Here, we focus on thin films of Heusler alloys as needed for magneto-electronic applications. Especially, Co- or Fe-based systems such as Co\(_2\)MnSi are known to be half-metallic or have at least a high spin polarization and a high Curie temperature making them appropriate as spintronic materials. In the present paper the influence of composition, disorder, and structural deformation on the magnetic properties is discussed from experimental as well as theoretical point of view. Since the quality of a spintronic device crucially depends on the interplay between the ferromagnet and the substrate the influence of different substrates (GaAs, MgO) on the electronic and magnetic properties is studied.
