Abstract We develop a phase-field model, integrating both micromagnetic and microelastic approaches. The model can capture the impact of eigen strain, applied stress and elastic inhomogeneity on the microstructure evolution in presence of an externally applied magnetic field. We use the model to simulate bicontinuous microstructure evolution during spinodal decomposition, with co-existing paramagnetic and ferromagnetic phases. The simulations confirm that the ferromagnetic phase tends to align itself in the direction of the applied magnetic field. Depending on elastic inhomogeneity, we also observe preferential alignment parallel or perpendicular to the applied stress. When these two fields are applied together, the alignment of the phases can precisely be controlled by changing strength and direction of either of the two.
