Description
We investigate the formation of magnetic polarons in the Kondo lattice model. Calculations are done in the framework of the bond particle formalism. We show that the quasiparticles correspond to spin polarons with a -dependent spatial extent. Polaron formation leads to a significant enhancement of the effective mass in the heavy parts of the band structure.
