Observation of magnetocoriolis waves in a liquid metal Taylor-Couette experiment
arXiv:1002.3791 · doi:10.1103/PhysRevLett.104.074501
Abstract
The first observation of fast and slow magnetocoriolis (MC) waves in a laboratory experiment is reported. Rotating nonaxisymmetric modes arising from a magnetized turbulent Taylor-Couette flow of liquid metal are identified as the fast and slow MC waves by the dependence of the rotation frequency on the applied field strength. The observed slow MC wave is damped but the observation provides a means for predicting the onset of the Magnetorotational Instability.
