Query: Probing magneto-elastic phenomena through an effective spin-bath
  coupling model   A phenomenological model is constructed, that captures the effects of
coupling magnetic and elastic degrees of freedom, in the presence of external,
stochastic perturbations, in terms of the interaction of magnetic moments with
a bath, whose individual degrees of freedom cannot be resolved and only their
mesoscopic properties are relevant.
  In the present work, the consequences of identifying the effects of
dissipation as resulting from interactions with a bath of spins are explored,
in addition to elastic, degrees of freedom. The corresponding stochastic
differential equations are solved numerically and the moments of the
magnetization are computed. The stochastic equations implicitly define a
measure on the space of spin configurations, whose moments at equal times
satisfy a hierarchy of deterministic, ordinary differential equations. Closure
assumptions are used to truncate the hierarchy and the same moments are
computed. We focus on the advantages and problems that each approach presents,
for the approach to equilibrium and, in particular, the emergence of
longitudinal damping.
