摘要：

The ground state of the Kondo-lattice model with one conduction electron is analyzed. A rigorous proof is given that this system forms an incomplete ferromagnetic order with S(tot) = (N - 1)/2 for antiferromagnetic exchange coupling. The wave function of the ground state is derived and some of its properties are discussed.
