Query: Phase Field Crystal Model for Magneto-Elasticity in Isotropic
  Ferromagnetic Solids   A new isotropic magneto-elastic phase field crystal (PFC) model to study the
relation between morphological structure and magnetic properties of pure
ferromagnetic solids is introduced. Analytic calculations were used to
determine the phase diagram and obtain the relationship between elastic strains
and magnetization. Time dependent numerical simulations were used to
demonstrate the effect of grain boundaries on the formation of magnetic
domains. It was shown that the grain boundaries act as nucleating sites for
domains of reverse magnetization. Finally, we derive a relation for coercivity
versus grain mis-orientation in the isotropic limit.
