High-throughput screening for antiferromagnetic Heusler compounds using density functional theory — •Jan Balluff, Markus Meinert, and Günter Reiss — Center for Spinelectronic Materials and Devices, Physics Department, Bielefeld University, Germany

Due to the exchange bias effect, antiferromagnetic compounds are of particular interest for the field of spintronics. Since Heusler compounds are a very versatile family of alloys, we attempt to find promising antiferromagnetic compounds unknown by now. We report on a high-throughput screening among the Heusler compounds for stable antiferromagnetic systems. Starting from a detailed evaluation of raw magnetic data for Heusler compounds extracted from the AFLOWLib [1], we extend the data by explicitly checking for stable antiferromagnetic ground states.
