The nonlinear partial differential equations describing the spin dynamics of
Heisenberg ferro and antiferromagnet are studied by Lie transformation group
method. The generators of the admitted variational Lie symmetry groups are
derived and conservation laws for the conserved currents are found via
Noether's theorem.
