Orbitally-driven insulator-metal transition in CuIr${}_2$S${}_4$: Temperature dependent transient reflectivity study

M. Naseska, P. Sutar, D. Vengust +4

Ultrafast transient reflectivity across the unusual three-dimensional Peierls-like insulator-metal (IM) transition in CuIr_{2}S_{4} was measured as a function of temperature. The l…
