Transition-metal substitution in semiconducting Ra8Ga16Ge30 clathrates Conference Paper

abstract

• We report magnetization, transport, and 71 Ga NMR properties of Ni- and Fe-substituted type-I Ba 6 Ge 30 Ga 16 clathrates. While Fe substitutes partially into the lattice, Ni substitutes readily for Ga, and we prepared samples with composition up to Ba 8 Ge 30 Ga 10 Ni 6 . Results indicate low-density metallic behavior for all samples, with little change in electronic structure caused by Fe or Ni substitution. NMR relaxation behavior (T 1 ) and Knight shifts in all samples exhibited a constant Korringa product (K 2 T 1 T) characteristic of metallic behavior with small exchange enhancement. 2005 American Institute of Physics.
