Moreover, recent observations of the quantum oscillations in the insulating state of Kondo insulators have come as a great surprise.

In all samples, the temperature dependence of the electrical resistivity is insulating at high temperatures and the resistivit","authors_text":"C. Tinsman, F. Iga, J. G. Analytis, J.
