Nonlinear stochastic relaxation dynamics in spin-crossover solid-state compounds

Abstract

A study of dynamic of spin-crossover solid-state compound has been carried out. The investigated macroscopic phenomenological model for molecular spin-crossover complexes with optical control parameter has been extended to the case of noise action. The noise-driven phase transition was observed. Also, ascertained was the role of additive noise as a main factor for suppressing the potential barrier height.
