Abstract Scope In the past, the Ising model was used to address the problem of ferromagnetic to paramagnetic phase transition. However, to reduce the computing cost, several assumptions were made. These assumptions include the consideration of only nearest neighbor spin interactions, and the exclusion of an external magnetic field and uncertainty effects. Furthermore, the Ising model is constructed without the presence of defects. The goal of this study is to use the mean field solution for exploring the magnetic phase transition problem using a higher order Ising model involving crystallographic defects in both 2D and 3D directions. The created model incorporates long-range interactions of spins while accounting for an external magnetic field and the effects of the uncertainty in the external field and temperature. The results of this work are expected to contribute to the robust design of magneto-mechanical materials used in extreme environments.
