Abstract: We have studied the acoustic Faraday effect in superfluid He up to significantly larger magnetic fields than in previous experiments achieving rotations of the polarization of transverse sound as large as 1710°. We report nonlinear field effects, and use the linear results to determine the Zeeman splitting of the imaginary squashing mode (ISQ) frequency in He- B. [ABSTRACT FROM AUTHOR]
