Alfven instability and micromagnetic islands in a plasma with sheared magnetic fields
The normal mode equation for coupled drift and Alfven waves in a finite-..beta.. nonuniform plasma with a sheared magnetic field is solved, in the slab geometry, to investigate the instability of slow Alfven waves. It is shown, that, besides having an appreciable growth rate, the instability also produces microscopic ''tearing'' of the rational surfaces which has important implications for anomalous transport.
