Coupled magnetic and electronic phase transitions. Total DOS of AFM (dotted line) and FM (bold line) relaxed structures for x =  (a) 2.5, (b) 2.75, and (c) 2.875. Note that FM always induces metallic characters regardless of the composition. (d) Expected phase diagram of SCO with oxidation from our optical study combined with DFT. It is compared with a previous dc-measurement²⁴.
