Query: Spin Dynamics of Layered Triangular Antiferromagnets with Uniaxial
  Anisotropy   The spin dynamics of the semiclassical Heisenberg model with uniaxial
anisotropy, on the layered triangular lattice with antiferromagnetic coupling
for both intralayer nearest neighbor interaction and interlayer interaction is
studied both in the ordered phase and in the paramagnetic phase, using the
Monte Carlo-molecular dynamics technique. The important quantities calculated
are the full dynamic structure function $S(\bf q, \omega)$, the chiral dynamic
structure function $S_{chi}(\omega)$, the static order parameter and some
thermodynamic quantities. Our results show the existence of propagating modes
corresponding to both $S(\bf q, \omega)$ and $S_{chi}(\omega)$ in the ordered
phase, supporting the recent conjectures. Our results for the static properties
show the magnetic ordering in each layer to be of coplanar 3-sublattice type
deviating from 120 degree structure. In the presence of magnetic trimerization
however, we find the 3-sublattice structure to be weakened alongwith the
tendency towards non-coplanarity of the spins.
