Abstract
It is a formidable task of material science to find materials suitable for spintronics applications. Candidates within the large group of perovskites are the ferrimagnetic double perovskites which combine high Curie-temperatures with half-metallic behavior. Research in this field is focussed particularly on strategies for tayloring ferrimagnetic double perovskites with still higher Curie-temperatures and new properties such as antiferromagnetic half-metallicity.
