Band splitting and relative spin alignment in bilayer systems

Influence of relative spin alignment on the band splitting and magnetic excitations in the bilayer correlated systems is studied. Splitting occures to be large or small depending on orientation of staggered spins of layers. Change of the ground state configuration with doping is shown. Behavior of the bilayer splitting in Bi-based cuprate allows to suppose that superconducting transition is accompanied by transformation of spin configuration of system.Comment: 9 pages, 3 figure
