Query: Influence of Roughening Transition on Magnetic Ordering   In the literature of magnetic phase transitions, in addition to a critical
point, existence of another special point has been discussed. This is related
to the broadening of interface between two different ordering phases and is
referred to as the point of roughening transition. While there exists good
understanding on equilibrium properties associated with this transition,
influence of this on nonequilibrium dynamics has not been investigated. In this
paper we present comprehensive results, from Monte Carlo simulations, on
coarsening dynamics in a system, over a wide range of temperature, in space
dimension d = 3, for which there exists roughening transition at a nonzero
temperature. State-of-the-art analysis of the simulation data, on structure,
growth and aging, shows that the onset of unexpected glass-like slow dynamics
in this system, that has received much attention in recent times, for quenches
to zero temperature, actually occurs at this transition point. This
demonstrates an important structure-dynamics connection in phase-ordering
dynamics. We compare the key results with those from d = 2, for which there
exists no non-zero roughening transition temperature. Absence of the above
mentioned anomalous features in the latter dimension places our conjecture on
the role of roughening transition on a firmer footing.
