Mobility of the antiferromagnetic large polaron
Abstract
The motion of an antiferromagnetic large polaron under an applied electric field is treated theoretically. It is shown that the motion of the 4f{hook} spin polarization is similar to that of antiferromagnetic domain wall motion. The results are described in terms of an extra effective mass which is due primarily to the 4f{hook} spin exchange energy. For a large polaron, the effective mass is very large. © 1970.
