MIXED VALENT SEMICONDUCTORS : SmB6
نویسندگان
چکیده
An overview is given of the experimental and theoretical evidence that SmB, is a homogeneously mixed valent semiconductor. It is emphasized that the experimental transport properties imply that the Fermi surface is either extremely small or non-existent, and that rather general theoretical considerations support the possibility of a gap at the Fermi level.

Collapse of the coherence gap in Kondo semiconductors
Kondo semiconductors exhibit a gap in their low-temperature excitation spectra, and can be modeled by the Anderson lattice model at half filling which shows a hybridization gap. The mixed-valent Kondo semiconductor SmB6 also shows in-gap magnetic excitations that exhibit the temperature dependence and dispersion that are expected from magnetic excitons. The gaps measured in the Kondo semiconduc...
متن کاملOptical study of c–f hybridization states in mixed-valent Yb compounds: metallic YbAl3 vs semiconducting YbB12
We have measured the optical conductivity spectra sðoÞ of YbB12 and YbAl3; which are typical mixed-valent Yb compounds. The measured sðoÞ spectra in the mid-infrared region are quite similar for the two compounds, with a pronounced peak centered near 0:2 eV: This result demonstrates that the Kondo semiconductor YbB12 and the highly metallic YbAl3 share very similar electronic structures near th...
متن کاملOn the Chemistry and Physical Properties of Flux and Floating Zone Grown SmB6 Single Crystals
Recent theoretical and experimental findings suggest the long-known but not well understood low temperature resistance plateau of SmB6 may originate from protected surface states arising from a topologically non-trivial bulk band structure having strong Kondo hybridization. Yet others have ascribed this feature to impurities, vacancies, and surface reconstructions. Given the typical methods use...
متن کاملThin films of topological Kondo insulator candidate SmB6: Strong spin-orbit torque without exclusive surface conduction
The advent of topological insulators (TIs), a novel class of materials that harbor a metallic spin-chiral surface state coexisting with band-insulating bulk, opens up new possibilities for spintronics. One promising route is current-induced switching of an adjacent magnetic layer via spin-orbit torque (SOT), arising from the large spin-orbit coupling intrinsically possessed by TIs. The Kondo in...
متن کاملLow-temperature magnetic fluctuations in the Kondo insulator SmB6
We present the results of a systematic investigation of the magnetic properties of the threedimensional Kondo topological insulator SmB6 using magnetization and muon-spin relaxation/rotation (�SR) measurements. The �SR measurements exhibit magnetic field fluctuations in SmB6 below �15 K due to electronic moments present in the system. However, no evidence for magnetic ordering is found down to ...
