Parametrically excited spin waves in an yttrium iron garnet (YIG) are good model objects to study nonlinear dynamics. Chaotic oscillations of this system can be controlled with a time-delayed feedback method. The feedback perturbation was added to the static magnetic field. This controlling process has been characterized by strange attractors. With increasing feedback gain, a fractal dimension of the strange attractor decreases from 2.9 to 1.1. This means that chaotic oscillations change to periodic oscillations successively. Further increase of feedback gain eventually produces chaotic oscillations again.
