The nonequilibrium phenomenon of phase ordering kinetics (or domain growth or coarsening) after a temperature quench is studied in FNs. The focus here is to investigate the role of coupling in pattern formation. The modeling is based on time-dependent Ginzburg–Landau equations for the coupled order parameters. Quenches from a high-temperature disordered phase are considered. Subsequently, the system coarsens by collision and annihilation of topological defects. A notable phenomenon, termed slaved coarsening, occurs when an intrinsically disordered component is driven to coarsen by an ordered one. Extensive numerical and analytical studies of morphologies, defect dynamics, and growth laws reveal unique features arising purely from magneto-nematic coupling.
