Abstract

Electronic and magnetic properties of the double perovskites La 2TIrO 6 (T=Mn, Fe, Co) are calculated ab initio and compared with experimental results. Using a self-consistent band-structure method within the local spin-density approximation (LSDA) total-energy and density-of-states (DOS) calculations are performed of ferromagnetic and antiferromagnetic spin configurations. Finally, we discuss the effect of ordering among the T and Ir sites by comparing two differently ordered structures.
