Energy landscape thermal equilibrium

The calculation of the thermal stability requires the estimation of transition rates between stable equilibrium states of the magnet. The calculation of transition rates needs a detailed characterization of the energy landscape along the most probable path which is taken by the system from its initial state to a final state. Henkelman and Jonsson [20] proposed the nudged elastic band method to calculate minimum energy paths. Starting from an... [Pg.115]

This function represents for given system parameters T, V, and AT the free-energy landscape in dependence of the components of the vector of relevant degrees of freedom Q. Minima in this landscape correspond to locally stable (metastable) equilibrium system states. Peaks in this landscape represent free-energy barriers. A structural transition requires the system to circumvent the barrier or to overcome it by a fluctuation with thermal energy that exceeds the barrier height. [Pg.50]
