Kondo Behavior of U in CaB $_{6}$

G. A. Wigger, E. Felder, S. Weyeneth +2

Replacing U for Ca in semiconducting CaB $_{6}$ 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 $_{6}$ , the Curie temperature $T_{C}$ decreases substantially with increasing dilution of the magnetic sublattice and is…

Electronic transport in EuB $_{6}$

G. A. Wigger, R. Monnier, H. R. Ott +2

EuB $_{6}$ is a magnetic semiconductor in which defects introduce charge carriers into the conduction band with the Fermi energy varying with temperature and magnetic field. We presen…
