A drastic increase in nh due to annealing was found. The increase in nh cannot be explained solely by the oxygen gain due to annealing, suggesting that delocalized holes are introduced into the CuO2 plane. A phase diagram of LESCO was redrawn against nh.}, pages = {075002-1--075002-2}, title = {Revisiting the Phase Diagram of T*-type La1−x/2Eu1−x/2SrxCuO4 using O K-edge X-ray Absorption Spectroscopy}, volume = {89}, year = {2020} }
