The Study of Magnetic Properties and Applications of II–VI Diluted Magnetic Semiconductor, Zn1–xMnxO Nanoparticles
Abstract: Ferromagnetism in II-VI diluted magnetic semiconductor, Zn1-xMnxO is studied. The magnetic behavior of this Diluted Magnetic Semiconductor (DMS) is determined by using the Heisenberg and the Green’s formalism. Heisenberg’s Model describes the Hamiltonian of the system in terms of spin density and excitons. In the same way, Green’s theorem is used for calculating magnetic quantities. These theorems are employed to estimate the origin of ferromagnetism in Zn1-xMnxO nanostructures. For spin- …

Ferromagnetism in II-VI Diluted Magnetic Semiconductor, Zn0.96Mn0.04O Nanostructures by Green’s Theorem
Abstract: Ferromagnetism in II-VI diluted magnetic semiconductor, Zn0.96Mn0.04O is studied. Using the Heisenberg principle, the spin exchange between the neighboring spin is discussed. Heisenberg’s model describes the Hamiltonian of the system in terms of spin density and excitons. Mathematically, magnetic parameters such as magnetizations and magnetic susceptibility are determined by Green’s function. Ferromagnetism is expected from sp-d exchange interactions (RKKY), point defects such as oxygen vacancies, and Zn interstitial and quantum …

COMPLEXATION AND ANTIBACTERIAL STUDY OF 1,3,4-OXADIAZOLE DERIVATIVE
Abstract: New metal complexes of Zn(II),and Ni(II) have been synthesized by reacting metal solutions with the ligand 2,5-substituted 1,3,4-Oxadiazoles in alcoholic medium. Molecular formulae of the complexes were determined and are further characterized by IR spectroscopy, magnetic susceptibility and molar conductance studies. Since two nitrogen atoms coordinate to the metal center, the ligand is termed as bidentate ligand.KEY WORDS: Complexes, Ligands, Transition metal complexes, Oxadiazoles.
