Abstract
In the framework of the two-dimensional Kondo lattice model with hoppings b etween first-, second-, and third-nearest neighbors the spin-polaron spectr um is investigated. A complex structure of a spin-polaron and an increase o f frustration in spin subsystem leads to the evolution in the excitation ba nd close to the evolution on hole hopping which is given by ARPES experimen ts in HTSC.
