AB  - Co2CrAl and Co2CrSi are amongst the most studied Heusler alloys due to their half-metallic character. These compounds are also well-known to present ferromagnetism with high Curie temperatures. We show using first-principles calculations that the creation of Cr antisites (Cr atoms at the Co sites) induces ferrimagnetism in these compounds without destroying the half-metallic character of these alloys. The reduction of the total spin moment causes lower external fields and thus smaller energy losses in realistic magnetoelectronic, also known as spintronic,devices.
