In metals, orbital motions of conduction electrons on the Fermi surface are quantized in magnetic fields, which is manifested by quantum oscillations in electrical resistivity. This …
Sm B 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 …
The inverted resistance method was used in this study to extend the bulk resistivity of S m B 6 to a regime where the surface conduction overwhelms the bulk. Remarkably, regardless of …

We investigated the crystal-electric field ground state of the 4 f manifold in the strongly correlated topological insulator SmB 6 using core-level nonresonant inelastic x-ray …
Resonant x-ray emission spectroscopy was used to determine the pressure dependence of the f-electron occupancy in the Kondo insulator SmB 6. Applied pressure reduces the f …
The Kondo insulator samarium hexaboride (SmB 6) has been intensely studied in recent years as a potential candidate of a strongly correlated topological insulator. One of the most …
The proximity effect at the interface between a topological insulator and a superconductor is predicted to give rise to chiral topological superconductivity and Majorana fermion …
We have carried out bulk-sensitive hard x-ray photoelectron spectroscopy measurements on in situ cleaved and ex situ polished SmB 6 single crystals. Using the multiplet structure in the …
We show 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 …
