| I will discuss types of dynamical magnetization processes of molecular magnets depending on the energy structure at the avoided level structure. So far we have studied a mechanism due to the non-adiabatic transition (Landau-Zener type) and a mechanism due to a kind of thermal process (Magnetic Feohn type). We will discuss the dependence of magnetic plateau on the parameters of the system. WE also study mechanisms of the energy gap and characteristics of magnetic ground state. I will also discuss on the dynamical properties of one-dimensional chains. |
