Abstract
This paper is an overview of some recent work done on the double perovskites. We discuss the physics of selected double perovskite compounds emphasizing the relevant interactions and resulting observable phenomena such as the magnetic order using different theoretical approaches. Spin-Orbit interaction, which is comparable to other relevant interaction strengths, plays a central role in determining the physics of such 4d-5d perovskites.
