Abstract

In this research it has been investigated the spin compensation points of a mixed spin-3 and spin-7/2 Blume-Capel Ising system on a square lattice. Magnetic phase transitions, in a molecular based magnet, are tested by using mean field method (MFM) Equilibrium magnetizations can be accomplished by minimizing free energy, which is also a significant technique for locating and inducing spin compensation points. On principles of Bogoliubov inequality of the free energy, it has been investigated the second-order phase transitions in the (DB / |J| , KBTC / |J|), or (DA /|J|, KBTC / |J|) planes, respectively. Distinctive ferrimagnetic traits, in specific, have been demonstrated focusing on the negative numbers of the various single-ion anisotropies interacting on the A− atoms and B− atoms, respectively.
