Three stable states simulated for 1D Spin-Crossover Nanoparticles using the Ising-Like model

International audienceIn the present work, numerical simulations for spincrossover 1D nanoparticles embedded in a matrix are presented anddiscussed in the framework of the Ising-like model taking into accountshort- (J), long-range (G) interaction as well as the interaction (L)between the surface molecules and the surroundings. Using a newalgorithm, detailed in this contribution, to calculate the density ofstates for each macro-state, we have obtained a three-state thermalbehaviour for some sets of parameters. We analyse the role of thesedifferent parameters, as well as the number of 1D SCO molecules, inthe monitoring of this particular behaviour
