The variational symmetries and conservation laws in classical theory of Heisenberg (anti)ferromagnet
Publikováno v:
Phys. Lett. A 292 (2002) 325-334
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 conservat

We suggest a method of derivation of the long-wave action of the model spin Hamiltonians using the non-linear partial differential equations of motions of the individual spins. According to the Vainberg's theorem the set of these equations are (forma
