Title: Kink model of state switching in quasi-one-dimensional nanosystems

A method for the analytical calculation of the kinetics of state switching induced by external field in quasi-one-dimensional systems has been developed. This method is based on the Kolmogorov approach, which was proposed to describe statistical crystallization. As applied to magnetic systems, it allows one to calculate magnetization curves and hysteresis loops. The results of analytical calculation are confirmed by stochastic Monte Carlo simulation, which also makes it possible to find characteristics of mixed domain states formed as a result of the multiple cycling of the external field amplitude.
