Abstract

The motion of a single hole in the antiferromagnetic ground state and in the paramagnetic state at high temperatures is studied in the Kondo-Hubbard model with Hund coupling. It is shown that the Hund coupling strongly reduces both band-width of the coherent state at the ground state and the mobility at high temperatures. Implications of the results to magneto-transport phenomena in manganites are presented.
