A new mechanism for nuclear spin diffusion via virtual spin excitons under the conditions of integer quantum Hall effect is proposed. This mechanism significantly enhances the range of nuclear spin interaction along the magnetic length, and therefore may explain the nuclear spin depolarization in a spin diode.
