Abstract:

The annealed magnetic mixture with random bonds whose distribution may be continuous function ρ(J) of the magnitude for the exchange integral J, is treated exactly. When the variance of the distribution increases, the temperature range in the ferromagnetic state of the mixture decreases. Three ferromagnetic transitions may exist for an appropriate distribution even in the square lattice. The crossing-over for the renormalized exponent is discussed.
