Iridate materials are at present the focus of interest because the combination of strong spin–orbit effects and many-body electronic correlations makes their physics non-trivial. Now, the density of states of Sr 3 Ir 2 O 7 is mapped out spatially using scanning tunnelling microscopy and spectroscopy...
