FIG. 1.

Time evolutions of (a) the width and (b) the rotation frequency of magnetic islands. Four cases are examined: (i) the tearing mode, (ii) the drift-tearing mode, (iii) the tearing mode with the magnetic perturbation, and (iv) the drift-tearing mode with the magnetic perturbation.

FIG. 2.

Contours of the magnetic flux surface [(a) and (b)], the (2,1) electrostatic potential [(c) and (d)], and the (2,1) vector potential [(e) and (f)] in the nonlinear saturation state. Two cases are examined: the tearing mode [(a), (c), and (e)] and the drift-tearing mode locked by the resonant magnetic perturbation [(b), (d), and (f)].

FIG. 3.

Radial profiles of radial electric fields around O-points of magnetic islands locked by resonant magnetic perturbations.

Image of FIG. 4.
FIG. 4.

Radial profiles of (a) radial electric fields and (b) stresses around the O-point of magnetic islands locked by resonant magnetic perturbations.

Image of FIG. 5.
FIG. 5.

Parameter dependence of the stress, the radial electric field shear, and the typical scale length of the radial electric field shear.
