Ferromagnetic,spin-glass and paramagnetic phases in diluted heisenberg ferromagnet with fluctuating exchange bonds

We construct a simple CPA for studying ferromagnets which simultaneously possess site and (isotropic) exchange bond disorders. We use the theory to study spin-wave stiffness in diluted ferromagnet with exchange amorphousness and analyze the structure of the interfaces between ferromagnetic, spin-glass and paramagnetic phases of such a system.
