Magnetic Field Induced Fermi Liquid In a Candidate Topological Kondo Insulator

ORAL

Abstract

Kondo insulators are expected to undergo an insulator-to-metal phase transition under strong magnetic fields. We show that Ce3Bi4Pd3 is a narrow gap Kondo insulator. Our high magnetic pulse-field transport and magnetization experiments reveal the destruction of Kondo coupling and the closing of the Kondo gap at a critical magnetic field, Bc ≈ 11 T. A Fermi liquid state emerges for fields beyond Bc, with a decrease in electronic correlations.
