Due to a combination of strong spin orbit coupling and electron correlations iridates such as Sr2IrO4 exhibit a range of exotic quantum states that can be tuned via their electronic and magnetic properties. Here, the authors investigate the resistive and Raman scattering properties of Co-doped Sr2IrO4 and provide evidence for quantum critical fluctuations in the system.
