| Abstract: | We report on a comprehensive optical, transport, and thermodynamic study of the Zintl compound Yb(14)MnSb(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. |
