The Kondo lattice model (KLM) is a typical model describing heavy fermionsystems. In this paper, we consider the interaction of phonons with the systemdescribed by the one-electron KLM. Magnetic properties of the ground state ofthis model are revealed in a rigorous form. Furthermore, we derive theeffective Hamiltonian in the strong coupling limit ($J\to \infty$) for thestrength of the spin-exchange interaction $J$; we examine the magneticproperties of the ground state of the effective Hamiltonian and prove that theAizenman--Lieb theorem concerning the magnetization holds for the effectiveHamiltonian at finite temperatures. Generalizing the obtained results, weclarify a mechanism for the stability of magnetic properties of the groundstate in the one-electron KLM system.
