Abstract

The dependence of the ground state spin of the 1D Kondo-like lattice model for stacked organometallic ferromagnets on the filling of pi -electron band is studied. For this purpose the effective Hamiltonians that describe the law-lying energy states of some doped ferromagnets are derived. For the lattice stack with N unit cells and p a-electrons that has the ground state spin S-0=N at p=N it is shown that S-0=S-max=(N+p)/2 at p
