Kondo Behavior of U in CaB
G. A. Wigger, E. Felder, S. Weyeneth +2
Replacing U for Ca in semiconducting CaB at the few at.% level induces metallic behaviour and Kondo-type phenomena at low temperatures, a rather unusual feature for U impuritie…

Percolation and Colossal Magnetoresistance in Eu-based Hexaborides
G. A. Wigger, C. Beeli, E. Felder +3
Upon substituting Ca for Eu in the local-moment ferromagnet EuB, the Curie temperature decreases substantially with increasing dilution of the magnetic sublattice and is…
