Abstract
Experimental images obtained by X-ray magnetic circular dichroism were digitized. The interaction energy of nanoparticles in the point dipole model was calculated. Particles having gray contrast in most cases have zero energy. Numerical calculations of the energy and heat capacity for the Apamea lattice were performed using the Metropolis algorithm in the limited radius dipole interaction model. The contribution of quantum fluctuations in the form of the Bose condensation temperature was calculated.

Keywords:
Ising model, XMCD images, GPU and CPU high performance calculations, statistical thermodynamics.
