  In this paper we study the coarsening dynamics of a spinor condensate
quenched into an easy-axis ferromagnetic phase by a sudden change in the
quadratic Zeeman energy. We show that applying a spin rotation prior to
changing the Zeeman energy accelerates the development of local order and
reduces heating. We examine the longitudinal spin ordering and the superfluid
ordering of the system and show that the respective order parameter correlation
functions exhibit dynamic scaling in the late time dynamics. Our results also
demonstrate that these two types of order grow at different rates, i.e.~with
different dynamic critical exponents. The spin domain area distribution is
calculated and is shown to have power law scaling behavior expected from
percolation theory.
