  Dynamics of nanoscopic arrays of monodomain magnetic elements is simulated by
means of the Pardavi-Horvath algorithm. Experimental hysteresis loop is
reproduced for the arrays of Ni, with the period 100 nm and the mean coercive
field 710 Oe.We investigate the box-counting fractal dimension of a cluster of
elements with given orientation of magnetic moments. No fractal behavior is
found. Also, the damage spreading technique is applied to check the
criticality. We find that the consequences of a local flip of one magnetic
element remainlimited to a finite area. We conclude that the system does not
show a critical behavior.
