Abstract: A Monte-Carlo simulation based on multi-state spin Potts model is performed to study the remanence enhancement effect in nano-sized ferromagnetic materials. Our simulation in a two-dimensional lattice reveals that the remanence enhancement is significantly dependent on the domain size R and the uniaxial anisotropy constant K. In the case of high uniaxial anisotropy, the remanence enhancement can be linearly scaled with the normalized exchange length d/R as the latter is small. A good consistency between this scaling and the theoretical prediction is presented.
