Evolution of electronic structure of Ru-doped single-crystal iridiates, Sr $_{2}$ Ir $_{1 - x}$ Ru $_{x}$ O $_{4}$

Seokbae Lee, Yu-Seong Seo, Eilho Jung +7

We investigated Ru-doped single-crystal 5 $d$ iridiates, Sr $_{2}$ Ir $_{1 - x}$ Ru $_{x}$ O $_{4}$ , at three different doping concentrations ( $x =$ 0.01, 0.07 and 0.10) using optical spectrosco…

Correlation effects obtained from optical spectra of Fe-pnictides using an extended Drude-Lorentz model analysis

Seokbae Lee, Yu-Seong Seo, Seulki Roh +3

We introduce an analysis model, an extended Drude-Lorentz model, and apply it to Fe-pnictide systems to extract their electron-boson spectral density functions (or correlation spec…

Magnetic-order-driven metal-insulator transitions in the quasi-one-dimensional spin-ladder compounds BaFe $_{2}$ S $_{3}$ and BaFe $_{2}$ Se $_{3}$

Seulki Roh, Soohyeon Shin, Jaekyung Jang +9

The quasi-one-dimensional spin ladder compounds, BaFe $_{2}$ S $_{3}$ and BaFe $_{2}$ Se $_{3}$ , are investigated by infrared spectroscopy and density functional theory (DFT) calculations. We ob…
