High pressure insulator-metal transition in SmB6
Abstract
We report the temperature and pressure dependence of the electrical resistivity and Hall constant of single crystal SmB6 for temperatures ranging from 1.2 K to room temperature, and pressures from 1 bar to 80 kbar. Our results indicate that at low pressures SmB6 is an insulator, but undergoes a sudden transition to metallic behavior at a pressure of 50 kbar. © 1994.
