We report on a comprehensive optical, transport, and thermodynamic study of the Zintl compound Yb{sub 14}MnSb{sub 11}, demonstrating that it is the first ferromagnetic Kondo lattice compound in the underscreened limit. We propose a scenario whereby the combination of Kondo and Jahn-Teller effects provides a consistent explanation of both transport and optical data.
