abstract
Magnetic properties of zig-zag ladder with XXZ anisotropy ,which is described by the Hamiltonian :
are studied. The Hamiltonian have been examined by analytical method when d=h=0. We compare two and three-legs ladder with a numerical investigation. We also discuss magnetic properties NH4CuCl3 in low temperature and propose models for NH4CuCl3.
Keywords : Zig-zag ladder, XXZ anisotropy , NH4CuCl3
