Effect of pressure on the correlation gap in a compound with intermediate valency SmB6
It is found that the correlation gap E9 in SmB6, which under normal pressure —4 meV, decreases under the action of pressure ρ and vanishes at/? ^55 kbar. In the pressure range ρ > 60 kbar, the resistance of SmB6 as a function of temperature R (T) exhibits a metallic behavior, which indicates a pressure-induced transition of samarium in SmB6 from the state with intermediate valency ν [v(Sm) = 2.6 at ρ = 0] to integer valency ν = 3 for ρ > 60 kbar.
