Magnetic properties of the mixed spin-32 and spin-12 anisotropic Heisenberg model

►We find eigenvalues and eigenvectors of the mixed-spin anisotropic Heisenberg model. ►We determine phase diagrams of the mixed-spin quantum Heisenberg and Ising models. ►We find difference between the quantum and classical models at low temperatures. ►Physically, we ascribe this difference to the quantum fluctuation effects.
