Spin-orbit coupling (SOC) is often either ignored or treated perturbatively in correlated electronic materials where 3d or 4d-orbitals are active. However, in materials with heavier atoms, SOC plays an important role in determining the ground state and often helps stabilize novel phases such as topological insulators, spin liquids, and novel magnetic states. In particular, the interplay between SOC and electronic interactions needs to be understood when these energy scales are comparable. Iridium oxides (iridates) with 5d-orbitals off er a playground to investigate their combined effects. In this talk, I will give a summary of recent theoretical and experimental developments on iridates, and then present a microscopic route to metal-insulator transition and magnetic properties observed in a series of layered perovskite iridates.
