Magnetization Process in the One-Dimensional Doped Kondo Lattice Model

Abstract

The magnetization process in the one-dimensional Kondo lattice model for the doped (n_{c}<1) case is studied by the density matrix renormalization group (DMRG) method. A rapid increase of the magnetization is caused by the collapse of the intersite incommensurate correlation of f spins. On the contrary, the intrasite f-c singlet correlation survives in the larger magnetic field. The crossover from large to small Fermi surfaces for majority and minority spins is observed, whereas the Fermi surfaces are always contributed by f spins. A magnetization plateau appears with the magnitude of 1-n_{c}. Both ends of the plateau are related to the coherence temperature and the Kondo temperature which are characteristic energies essential in heavy electron systems.
