Event details

Research into iridium (IV) oxides, such as Sr2IrO4, Eu2Ir2O7 and Ca4IrO6, is currently of great interest as the iridates show magnetic ordering that is thought to be facilitated by the presence of a spin-orbit induced Jeff=1/2 Mott-insulating state. Sr3Ir2O7 is one such compound and is a small band gap semiconductor that antiferromagnetically orders below 287K. Sr3Ir2O7 also belongs to the same structural family as La2CuO4, which becomes metallic and superconducting upon doping with strontium. In this talk I discuss the effects of substituting small amounts of strontium for lanthanum on the magnetic and electronic properties of (Sr3-xLax)3Ir2O7.

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
