SmB_{6} is a candidate topological Kondo insulator that displays surface conduction at low temperatures. Here, we perform torque magnetization measurements as a means to detect de Haas-van Alphen (dHvA) oscillations in SmB_{6} crystals grown by aluminum flux. We find that dHvA oscillations occur in single crystals containing embedded aluminum, originating from the flux used to synthesize SmB_{6}. Measurements on a sample with multiple, unconnected aluminum inclusions show that aluminum… Expand
Metallic islands in the Kondo insulator SmB6
The predicted interplay between Kondo physics and non-trivial topology in SmB$_{6}$ has stimulated many experimental reports, some of which are in apparent contradiction. The origin of the disputeExpand
Crystal Growth by the Floating Zone Method of Ce-Substituted Crystals of the Topological Kondo Insulator SmB6

It is shown that novel low temperature properties of bulk SmB_{6}, including the sudden growth of the de Haas-van Alphen (dHvA) amplitude (and heat capacity) at millikelvin temperatures, signal the presence of a highly asymmetric nodal semimetal. Expand
Kondo Breakdown and Quantum Oscillations in SmB_{6}.
It is argued that topological surface states permit us to reconcile the various data with bulk transport and spectroscopy measurements, interpreting the low temperature upturn in the quantum oscillation amplitudes as a result of surface Kondo breakdown and the high frequency oscillations as large topologically protected orbits around the X point.

Quantum Oscillation in Narrow-Gap Topological Insulators.
A two-band model with inverted band structure is shown that the periodically narrowing hybridization gap in magnetic fields can induce the oscillation of low-energy density of states in the bulk, which is observable provided that the activation energy is small and comparable to the Landau level spacing.

Observation of possible topological in-gap surface states in the Kondo insulator SmB6 by photoemission
By performing angle-resolved photoemission spectroscopy experiments, several dispersive states within the hybridization gap of SmB6 show negligible kz dependence, which indicates their surface origin, and photoemissions circular dichroism experiments suggest that the in-gap states possess chirality of the orbital angular momentum.
