Temperature-dependent $f$-electron evolution in CeCoIn${}_5$ via a comparative infrared study with LaCoIn${}_5$

Myounghoon Lee, Yu-Seong Seo, Seulki Roh +6

We investigated CeCoIn${}_5$ and LaCoIn${}_5$ single crystals, which have the same HoCoGa${}_5$-type tetragonal crystal structure, using infrared spectroscopy. However, while CeCoIn${}_5$…
