A quantum simulation model was developed and employed in this work to study the magnetism of an assumed 3d nanoparticle, which consists of an antiferromagnetic core and a ferromagnetic shell. The calculated magnetic structures, specific heat, magnetization and hysteresis curves are reasonable physically, demonstrating the correctness of the quantum model and the applicability of the simulation algorithm.
► A quantum simulation model is used here to study the magnetic properties of a 3d nanomagnet. ► The self-consistent algorithm employed here is much faster than Monte-Carlo simulation. ► The calculated magnetic structures, hysteresis, etc., are reasonable physically. ► Two different magnetic transition temperatures for the MaMa and McMc are found in simulation. ► The peaks in the magnetic specific heat curve appear away from the transition temperatures.
