Abstract:
The metal-non-metal transition in Kondo insulators of the type (Ce1-xLax)3Bi4Pt3 is studied as a function of the La (Kondo hole) concentration x. We explore the transition under variation of the applied magnetic field, the pressure, and the temperature. The many-body effects are treated by diagonalizing the site Hamiltonian and embedding this solution into the lattice, using the chain approximation. The alloy states at the Fermi energy are obtained using a real-space renormalization technique. The metal-insulator transition produced by the incorporation of La impurities is explained by the appearance of a delocalized level inside the conduction band rather than by the creation of an impurity band at the gap.
