Low temperature properties of a new compound based on (Yb, Zr)B12 substitution
Abstract
The thermodynamic, kinetic, and magnetic characteristics of (Yb, Zr)B12 have been investigated in detail in the temperature range from 4 to 300 K to reveal the effect of the band structure on the properties of the YbB12 Kondo insulator ground state. It is found that electron doping due to 20% substitution in the Yb sublattice significantly changes the properties of the low-temperature ground state of YbB12 Kondo insulator and only slightly affects the high-temperature spin-fluctuating state forming at T > 50 K.
