摘要：

The magnetic and magnetotransport properties of nanocomposite (Co)x(SiO2)1-x films have been investigated. Small-angle neutron scattering study showed that fractal magnetic structures begin to form near the percolation threshold. In the range of the structural percolation threshold, the size of the magnetically correlated regions exceeds several times the structural size of Co grains. © Allerton Press, Inc. 2007.
