Superparamagnetism and Monte Carlo simulations
Abstract
We revise the basic concepts beneath the idea of superparamagnetism and the suitability of Monte Carlo (MC) simulations to study superparamagnetic (SPM) properties. Starting with the description of the characteristic features of the single-domain SPM entities, their general magnetic-field and temperature-dependent magnetic properties are discussed. Then, the use of a MC technique for studying SPM properties is presented, starting with a general approach to MC methods and introducing the Metropolis algorithm as an adequate tool for reproducing SPM features. Special attention is paid to the role played by the computational time MC steps on the simulations.
