Hybridization gap and $f$-electron effect evolutions with Cd- and Sn-doping in CeCoIn${}_5$ via infrared spectroscopy

Myounghoon Lee, Yu-Seong Seo, Seulki Roh +4

We investigated hole (Cd)- and electron (Sn)-doped CeCoIn${}_5$ (CeCo(In${}_{1-x}{T}_x$)${}_5$ ($T$ = Cd or Sn)) using infrared spectroscopy. Doping-dependent hybridization gap distributio…
