Structural disorder in two-dimensional XY-model creates an anomalous slowing down in the process of critical relaxation. Dynamic dependences of the correlation length ξ(t) show slow growth with an "effective" dynamical critical exponent z > 2. For a pure system, it has been shown that a detailed consideration of the vortex dynamics leads to deviations from the known dependence ξ(t) ∼ (t/ln t)1/2.
