Phase diagrams of the diluted and random-bond Ising model
Ligia Edith Zamora, German Antonio Pérez Alcázar, Alberto Bohorquez +2 more
The quenched-bond disordered Ising model is studied by means of the mean-field renormalization-group approach. Besides dilution and ferromagnetic random bond, the probability distribution function also includes two extra competing random bonds which can be ferromagnetic or antiferromagnetic, depending on the sign of some competing parameters. The critical temperature against ferromagnetic bond concentration phase diagrams are analyzed for several values of the theoretical parameters.
