Qualitative Theory of Dynamical Systems for Control of Magnetic Memory Elements

Resumo

The unified approach to the description of magnetization dynamics in the free layer of a magnetic memory element is developed. For this purpose, the analysis of the singularities of the dynamical system is used as a basis. This approach provides the possibility to classify the dynamical modes of the magnetization dynamics and to determine the threshold values of the field and current for changing the type of dynamics.
