Title: Magnetic field-tuned Fermi liquid in a Kondo insulator

Abstract

Kondo insulators are expected to transform into metals under a sufficiently strong magnetic field. The closure of the insulating gap stems from the coupling of a magnetic field to the electron spin, yet the required strength of the magnetic field–typically of order 100 T–means that very little is known about this insulator-metal transition. Here we show that Ce₃Bi₄Pd₃, owing to its fortuitously small gap, provides an ideal Kondo insulator for this investigation. A metallic Fermi liquid state is established above a critical magnetic field of only B_c ≈ 11 T. A peak in the strength of electronic correlations near B_c, which is evident in transport and susceptibility measurements, suggests that Ce₃Bi₄Pd₃ may exhibit quantum criticality analogous to that reported in Kondo insulators under pressure. Metamagnetism and the breakdown of the Kondo coupling are also discussed.

Intrinsic metallic behavior above 50 tesla in a Kondo insulator

Conference Boebinger, G S ; Passner, A ; Canfield, P C ; ...

Interactions between localized and itinerant electrons give rise to a variety of classes of materials, including the heavy fermion metals and the Kondo insulators. In the Kondo insulators, a broad, half-filled conduction band is intersected by a nearly dispersionless f-level. Hybridization and correlations give rise to a low temperature quenching of the localized spins accompanied by a loss of carriers. Extremely high magnetic fields should destroy the Kondo interaction (antiferromagnetic coupling to the localized moment). For this reason, the authors have measured, in pulsed magnetic fields of 61 T, the longitudinal, transverse, and Hall resistivity of Ce{sub 3}Bi{sub 4}Pt{sub 3}.more »« less
Pressure-induced concomitant topological and metal-insulator quantum phase transitions in Ce3Pd3Bi4

Journal Article Xu, Chenchao ; Cao, Chao ; Zhu, Jian-Xin - npj Quantum Materials

Abstract The electronic property and magnetic susceptibility of Ce ₃ Pd ₃ Bi ₄ were systemically investigated from 18 to 290 K for varying values of cell volume using dynamic mean-field theory coupled with density functional theory. By extrapolating to zero temperature, the ground state of Ce ₃ Pd ₃ Bi ₄ at ambient pressure is found to be a correlated semimetal due to insufficient hybridization. Upon applying pressure, the hybridization strength increases and a crossover to the Kondo insulator is observed at finite temperatures.

Spin-hole doping in the Kondo insulator Ce{sub 3}Bi{sub 4}Pt{sub 3} studied by neutron scattering

Conference Severing, A ; Perring, T ; Thompson, J D ; ...

To investigate the effect of non-magnetic impurities on gap formation and stability in Kondo insulators, we have performed inelastic neutron scattering experiments on (Ce{sub 1-x}La{sub x}){sub 3}Bi{sub 4}Pt{sub 3}, with x = 0.0, 0 1, 0.25 and 1.0. Data were collected at the Rutherford spallation source using incident neutron energies of 30 and 100 MeV and with the sample temperature fixed at 10K, well below {Delta}g/k{sub B}. The gap edge, defined from the rapid onset of scattering intensity, decreases quadratically with La content. However, the energy {Delta}{sub g} at which the magnetic intensity reaches one-half its maximum value scales withmore »« less

Influence of a Kondo-hole impurity band on magnetic instabilities in Kondo insulators

Journal Article Schlottmann, P - Physical Review, B: Condensed Matter

Kondo insulators like Ce{sub 3}Bi{sub 4}Pt{sub 3} and CeNiSn are compounds with small-gap semiconductor properties. The Kondo insulator is described by the nondegenerate symmetric Anderson lattice with, on average, two electrons per site within Kotliar and Ruckenstein{close_quote}s mean-field approximation in terms of four slave bosons per site. A Kondo hole is the charge neutral substitution of a rare earth or actinide atom by a nonmagnetic analog. An isolated Kondo hole gives rise to a bound state in the gap, which pins the Fermi level and has magnetic properties. A finite concentration of Kondo holes generates an impurity band in themore »« less
