  We derive a spin chain Hamiltonian from a fast spinning string in the
marginally deformed AdS(3)X S(3). This corresponds to a closed trajectory swept
out by the SU(2) or SL(2) spin vector on the surface of one-parameter deformed
two-sphere or hyperboloid in the background of anisotropic magnetic field
interaction. In the limit of small deformation, a class of general
Landau-Lifshitz equation with a nontrivial anisotropic matrix can be derived.
