Kondo Lattice Behavior in the Ordered Dilute Magnetic Semiconductor Yb_{14-x}La_xMnSb_{11}

B. C. Sales, P. Khalifah, T. P. Enck +4

We report Hall, magnetic, heat capacity and doping studies from single crystals of Yb_14MnSb_11 and Yb_13.3La_0.7MnSb_11. These heavily doped semiconducting compounds are ferromagn…
