About degrees of freedom of magnetization at modelling of magnetic structure quasi-one-dimensional systems

The question on legitimacy and restrictions of widely applied one-angular model in the numerical description of distribution of magnetization in one-dimensional and quasi- one-dimensional systems is discussed. Special cases of magnetic systems, in which application of two-angular model of the numerical analysis necessarily are considered. The general expressions hamiltonian for magnetization modelling nanowires in both models are offered.
