✦ Synopsis

The magnetic properties of interfacial regions between ferromagnetic nanograins and the residual matrix in nanocrystalline materials, are modelled using Monte Carlo simulation. The exchange coupling between matrix and nanograin influences differently the nanograin surface and the interface between nanograin and matrix. This behaviour has been explained in terms of a polarisation mechanism of the interfacial zones leading to magnetic correlation between spins of nanograin surface and core.

An algorithm for efficient Monte Carlo simulation of a globular protein is proposed. The algorithm was developed by combining the smart Monte Carlo of Rossky et al. with the scaled-collective-variable Monte Carlo method of Noguti and Go. The results of the simulations demonstrated that the combined

Monte Carlo simulations have been carried out on DNA oligomers using an internal coordinate model associated with a pseudorotational representation of sugar repuckering. It is shown that when this model is combined with the scaled collective variable approach of Noguti and Go, much more efficient si
