The iridates (eg Sr2IrO4, Sr3Ir2O7 ...) have recently attracted the attention of the scientific community due to the presence of a strong spin-orbit coupling and strong electronic interactions that give rise to original physical properties as the high Tc superconductivity or the state of topological insulator. We explore in detail the impact of a strong spin-orbit coupling in these compounds by synthesizing single crystals with a method of self-flow and thin films by PLD technique and by studying the magnetic and transport properties of these oxides.
On these issues, the group has developed national and international collaborations in particular with: LPS-Orsay; Soleil; MPQ-Paris7; LLB-Saclay ;
