Ultrafast selective mid-infrared sublattice manipulation in the ferrimagnet $FeC{r}_2{S}_4$

Davide Soranzio, Matteo Savoini, Fabian Graf +6

$FeC{r}_2{S}_4$ is a ferrimagnet with two oppositely ordered spin sublattices (Fe and Cr), connected via superexchange interaction, giving a non-zero net magnetic moment. We show, usin…
