Anomalous 3D bulk AC conduction within the Kondo gap of SmB${}_6$ single crystals

N. J. Laurita, C. M. Morris, S. M. Koohpayeh +5

The Kondo insulator SmB${}_6$ has long been known to display anomalous transport behavior at low temperatures, T$<5$ K. In this temperatures range, a plateau is observed in the dc re…
