We present a detailed theory of induced persistent current produced by
hyperfine interaction in mesoscopic rings based on a 2D-electron (hole) gas in
the absence of external magnetic field. The persistent current emerges due to
combined action of the hyperfine interaction of charge carriers with polarized
nuclei, spin-orbit interaction and Berry phase.
