摘要: Abstract The various types of magnetizations a four-sublattice mixed-spin Heisenberg ferrimagnetic system are investigated with the help double-time temperature-dependent Green’s function technique. One obtains first-order phase transitions from states to or ferromagnetic respect choice parameters in Hamiltonian. exhibits one-, two- and three-compensation temperatures where sublattice compensate each other at one- more-points. We have managed obtain three different spin configurations absolute temperature. Moreover, we observed so-called frustrated spin.
