Abstract Scope |
Ferromagnetic materials are widely used in magneto-mechanical devices such as sensors, motors, generators, and transformers. However, their magnetism reduces drastically when ferromagnetic-paramagnetic phase transition occurs at the critical Curie temperature. This phase transition is described by an Ising model which formulates the effects of the external magnetic field and interactions between the magnetic spins. However, the uncertainties associated with the ambient temperature and external magnetic field lead to a phase transition zone rather than a single critical phase transition point. To the best of our knowledge, the effects of these external uncertainties, as well as the long-range interactions among the magnetic spins, on the phase transition behavior have never been explicitly modeled. This study presents an Ising model formulation for 2-D magnetic materials by incorporating the effects of long-range interactions between the spins and the external parameter (temperature and external magnetic field) uncertainties on the ferromagnetic-paramagnetic phase transitions. |
