Abstract

Nonlinear magneto-optical rotation (NMOR), an all-optical technique now finding its use in sensitive magnetometry, is light-intensity-dependent rotation of the polarization plane of linearly polarized light upon its propagation through a medium placed in a magnetic field. NMOR technique enables measurements of magnetic field from 0 to 50 muT with the expected sensitivity of 10^-14 T Hz^-1/2.
