Optical study of interactions in a d-electron Kondo lattice with ferromagnetism
arXiv:cond-mat/0507693 · doi:10.1103/PhysRevLett.95.046401
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 scenerio whereby the combination of Kondo and Jahn-Teller effects provides a consistent explanation of both transport and optical data.
