Abstract
The Richardson plots method is employed to measure the fractal dimensions D of the surface of magnetic dielectric film fractured by excimer laser irradiation near the ablation threshold. It is shown that the fractured surfaces are fractal character. The value of D decreases while the laser pulse number increases. This relation may reflect how the fractured surface changes from irregular structure to regular structure with laser pulse number.
