Co 2 ‐based Heusler compounds with 27.8 valence electrons exhibit an exceptional electronic structure that makes them interesting materials for the application in spintronics. Co 2 Cr 0.6 Fe 0.4 Al is the most prominent example of this particular family of compounds. In this article new materials of this class are tested with respect to their structural and magnetic properties. X‐ray diffraction, Mössbauer spectroscopy, energy dispersive X‐ray spectroscopy, and SQUID magnetometry were carried out to characterize the compounds. The use of Co 2 Fe 0.45 Ti 0.55 Ge as a new material in spintronic devices is suggested.
