We have developed a new quantum Monte Carlo approach and utilized it to calculate the magnetic structure, magnetization, and specific heat, etc., of nanoparticles composed of 3d magnetic ions. For comparison, we also performed simulations with the self-consistent computational algorithm which we proposed recently.

The calculated results obtained with the two methods are identical, verifying their correctness. We also found that the combination of the two above algorithms can improve the computational efficiency considerably and have more general applicability.
