Phys. Rev. Lett. 81, 5788–5791 (1998)Nonlinear Magneto-optic Effects with Ultranarrow WidthsReceived 17 July 1998; published in the issue dated 28 December 1998 Several dispersionlike features in the magnetic field dependence of the nonlinear magneto-optic effect were observed in an experiment performed on rubidium atoms contained in a vapor cell with antirelaxation coating. The narrowest feature has effective resonance width γ = gμΔBz≈2π×1.3Hz, where ΔBz≈2.8μG is the peak-to-peak separation. The observed nontrivial dependence of the magneto-optic effect on transverse magnetic fields is discussed. The results of this work may be applied to low-field magnetometry, to parity and time reversal invariance violation experiments, etc. © 1998 The American Physical Society URL:
