Sonoluminescence in High Magnetic Fields

Abstract
We have made a detailed study of sonoluminescence (SL) in high magnetic fields. In magnetic field sweeps at constant levels of acoustic drive, SL disappears above a pressure-dependent threshold magnetic field. Sweeps of acoustic drive at fixed magnetic fields show that the upper and lower bounds of forcing pressure that determine the region of SL increase dramatically with magnetic field. This interplay between acoustic and magnetic fields suggests that the primary effect of magnetic fields on SL is to alter the condition for stable bubble oscillations.
