Core/shell Fe98B2 nanoparticle has been constructed by molecular dynamics with pair Pak-Doyama potential under free boundary condition. The core/shell Fe98B2 nanoparticles with different crystallized factions were prepared by annealing from amorphous core/shell nanoparticle sample. The magnetic properties as magnetization moment, energy, heat capacity and magnetic susceptibility have been investigated by Ising model show the dependence of magnetic behaviors on shell thickness, on exchange interaction.
