Dynamical technique is applied for the third layer of 3He absorbed on the surface of graphite (kagome lattice) with 1D and multidimensional mapping. The existence of different magnetization plateaus are obtained for solid 3He. The maximum Lyapunov exponent has a plateau, and it coincides with the plateau dependent on the magnetic field. It is studied the super-stable cycles for non-integer values of Q-state Potts and Three-site Anti-ferromagnetic models. A particular attention is devoted to the period three window. The phase transition is observed in the supercritical point for multi-dimensional rational mapping of the spin-1/2 Ising-Heisenberg model on a diamond chain characterizing natural azurite, at T → 0 and the absence of a magnetic field in the anti-ferromagnetic case.
