Abstract

The role of hybridization effects in a system of highly correlated electrons is studied. It is shown that a narrow band of heavy fermions is formed within the hybridization gap due to strong scattering of d-electrons by spin fluctuations. The heavy-fermion states undergo the Anderson localization with increase in the spin and charge-density fluctuations. The electron-phase transformations into La0.65Ca0.35MnO3 are discussed on the basis of the proposed mechanism.
