Ground state and excitations of the 1D kondo-like lattice model for doped organometallic ferromagnets

摘要

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 low-lying energy states of some doped ferromagnets are derived. For the lattice stack with N unit cells and p #pi#-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
