Revisiting the phase diagram of T*-type La $_{1 - x /2}$ Eu $_{1 - x /2}$ Sr $_{x}$ CuO $_{4}$ using Oxygen $K$ -edge X-ray absorption spectroscopy

Shun Asano, Kenji Ishii, Kohei Yamagami +3

Oxygen $K$ -edge X-ray absorption spectroscopy measurements were conducted on T*-type La $_{1 - x /2}$ Eu $_{1 - x /2}$ Sr $_{x}$ CuO $_{4}$ (LESCO) to estimate the hole density ( $n_{h}$ ) and in…
