Subject:  Magnetic order in the iron pnictides and the impact of spin-orbit coupling

The iron pnictides represent a new family of unconventional superconductors in which superconductivity appears in close proximity to a magnetically ordered phase. In this talk I will review the magnetic order of the iron pnictides and discuss recent discoveries in the magnetic phase diagram, focusing on the reorientation of magnetic moments observed to occur in hole-doped compounds. Considering the impact of magnetic fluctuations on the phase diagram I will argue that even the modest spin-orbit coupling observed in iron pnictides has important consequences and cannot be neglected.
