Evidence for strongly coupled charge-density-wave ordering in three-dimensional RE5Ir4Si10 compounds by optical measurements

Riccardo Tediosi, Fabrizio Carbone, A. B. Kuzmenko +3

We report optical spectra of Lu${}_5$Ir${}_4$Si${}_{10}$ and Er${}_5$Ir${}_4$Si${}_{10}$, exhibiting the phenomenon of coexisting superconductivity or antiferromagnetism and charge density wav…
