Abstract: The influence of fractal clusters of a normal phase on the dynamics of vortices in a percolation superconductor is considered. It is established that a vortex glass state is formed in superconductors with a fractal cluster structure. The vortex glass phase can be identified by the initial part of its current-voltage characteristic. The dependence of the glassy exponent on the fractal dimension of normal phase cluster boundaries is found.
