Abstract: Three sizes of center decorated tetragonal nanoparticles are described by the transverse Ising model with the anisotropy. The phase diagram, the magnetization and the magnetic susceptibility for different sizes nanoparticles are studied within the effective field theory with correlations. The results show the size and anisotropy have different effects on the system, such as the reentrant on phase diagram and depressed saturation magnetization.
