- Abstract
Using the classical Heisenberg model and Monte Carlo simulations in the canonical ensemble, the effect of form, finite-size, and surface roughness on magnetization is investigated for ferromagnetic nanoparticle with uniaxial anisotropy and different nanoparticle shapes. In this work, cubical and spherical nanoparticles are considered; we have considered a simple nanoparticle where each site is occupied by a classical Heisenberg spin. Our numerical results show that the nanoparticle size and surface roughness have an impact and a considerable influence on the magnetic properties of these nanoparticles. But the influence of nanoparticle shapes is less significant when comparing magnetic behavior for cubical and spherical forms of the particle in a smooth or rough surface.
