Abstract

We explore the ultrafast optical response of Yb14MnSb11, providing further evidence that this Zintl compound is one of the first examples of a ferromagnetic under-screened Kondo lattice. These experiments also provide the first demonstration of coupling between an optical phonon and the Kondo effect.
