Analysis of atomic structure of amorphous metals in the frame of percolation theory

Atomic structure of Re-Tb amorphous alloys (AA) was investigated by computer simulation method. The analysis of atomic structure of AA was performed within the framework of percolation theory and fractal geometry. Atomic clusters were determined as atomic groups of one type that are in the distances from each other not exceeding a percolation radius rc. In the simplest case atoms belong to one cluster if they are in the immediate contact with each other. The size distribution of clusters, probability of belonging of the atom to the largest cluster, fractal dimensionality of the percolation cluster and concentration dependence of percolation radius were calculated. Correlation between magnetic properties of AA and their cluster structure was established
