Spinel type, rhombohedral and tetragonal defective. The ternary compounds of the family II-III 2 -VI 4, depending on the number of tetrahedralĪnd octahedral sites for cations, may crystallize in three main structures: cubic Compounds of this family are characterized by a variety of crystalline structures according to the composition cation-anion and to the position of the cations in sites with tetrahedral or octahedral coordination. synthesized a new family of compounds of type II-III 2 -VI 4 from the mixture of (II-VI) + (III 2 VI 3 ). Magnetic semiconductors are viewed as enabling materials for magneto-electronic devices and technology. There is a large practical motivation for the study of magnetic semiconductors due to their potential for combining semiconducting and magnetic behavior in a single material system. From the standpoint of the latter, crystal lattice energies are important in considering the stability of new materials and reflect the natural tendency towards the organization of matter 1 meanwhile the energy gap is important to determine the region of the light spectrum where the semiconductor can be applied like photonic device. These parameters have been investigated not only experimentally, but also theoretically. The knowledge of physics parameters of semiconductor compounds is of great interest in order to evaluate their potential use in a wide class of optoelectronics devices.
