 Theoretical calculation of magnetic phase diagram of the multiple interaction system (Fe0.65Ni0.35)1−xMnx alloy series using the Ising model and the mean-field renormalization group (MFRG)Juan Esteban Bedoya Rodríguez and Germán Antonio Pérez Alcázar Physica A: Statistical Mechanics and its Applications, 2025, vol. 669, issue C Abstract: Starting from the model used in previous articles, the (Fe0.65Ni0.35)1−xMnx system was fitted using the mean-field renormalization group method (MFRG)[1], considering a linear bond energy between spins and neglecting anisotropy interactions in the lattice. Experimental data from its respective reported magnetic phase diagram were taken as the basis for the fit. The results showed a good fit, with a mean square error (χ2) less than 0.034 across all the adjusted transition curves, demonstrating high graphical accuracy. Furthermore, an approximation to the bond energy of all its distinct types of bonds was obtained, aligning with the behaviour that was proposed in previous studies.
