Abstract

In this chapter, we focus on the study of influence of surface on thermal-induced spin-crossover phenomenon which is a subject of a broad and current interest. The modified Ising-like model of spin-crossover solids with the ligand field as function of the molecule positions and random component on the surface has been proposed. By means of the adapted Metropolis Monte Carlo algorithm, the thermal spin transition curves were calculated. The detailed kinetics of switching between high-spin and low-spin molecules have been analyzed from spin configuration at transition temperature, which gives a general idea about contribution of molecules from the surface and inside the lattice into resulting magnetization of the systems. The behavior of hysteresis loop for various surface coupling and fluctuation strengths has been described.
