Diluted and random-bond Ising model for the Fe-Al disordered alloys

A quenched disordered Ising model with a distribution function that includes dilution and random bonds is studied through the mean-field renormalization-group approach. Random bonds are considered through a ferromagnetic exchange interaction between nearest-neighbor spins (NN) and an antiferromagnet...

Beschreibung
Zusammenfassung:	A quenched disordered Ising model with a distribution function that includes dilution and random bonds is studied through the mean-field renormalization-group approach. Random bonds are considered through a ferromagnetic exchange interaction between nearest-neighbor spins (NN) and an antiferromagnetic exchange interaction between next-nearest-neighbor spins (NNN). The phase diagrams are obtained and the results are applied to Fe--Al disordered alloys.
