A specific tail near the zero frequency in the noise spectrum is predicted; the amplitude and the width being of the same order of magnitude as the recently reported peak in the noise spectrum at the spin Larmor frequency. The ratio of the spectrum amplitudes at zero- and Larmor frequencies is shown to be a convenient tool for testing theoretical predictions. © 2004 The American Physical Society URL:
