Abstract:
The magnetic behaviours of a mixed Blume-Capel Ising ferrimagnetic system on a square lattice having spins 2 1 Ai and spins23,21 Bj , in the absence and presence of an external magnetic field, are investigated, respectively. Our results which are examined have interesting features depending on negative values of anisotropy field. The longitudinal magnetic fields dependence of the spin compensation temperature is the essential substance of research. It is worth to note that in this model, the contribution of magnetic free energy to the thermodynamic stability of the mixed spin ferrimagnet with first nearest neighbour interaction is indicated
