Topological destruction of the phase transition to the spin-glass state in amorphous alloys with an asymmetric distribution of exchange interactions

It is shown that an increase in the asymmetry in the distribution of exchange interactions reduces the real magnetic dimension of bulk samples of amorphous spin glasses FeNi and FeMn, which attains its lowest critical value D _L =2.51±0.12 near the percolation threshold of infinite ferromagnetic clusters. The experimentally obtained result is in good agreement with calculations made using computer experiments.
