Transport properties in CeOs${}_4$Sb${}_{12}$: Possibility of the ground state being semiconducting

H. Sugawara, S. Osaki, M. Kobayashi +4

We have measured both magnetoresistance and Hall effect in CeOs${}_4$Sb${}_{12}$ to clarify the large resistivity state ascribed to the Kondo insulating one and the origin of the phase…
