the electronic and magnetic properties of the hypothetical compounds of mc (m=al, ga and in) are investigated by using first-principle calculations and pseudopotential plane wave self-consistent field method based on density functional theory. in order to find the most stable phase of mc (m=al, ga and in), we study them in zinc-blende (zb), rocksalt (rs), wurtzite and nias crystal structures. w...
Present spintronic research [1,2,3] involves virtually all materials families but ferromagnetic semiconductors are particularly attractive as they combine resources of both semiconductors and ferromagnets. We describe here recent studies of ferromagnetic Crand Mn-based II-VI diluted magnetic semiconductors (DMS) excluding, however, oxides that are subject of another presentation [4]. Properties...
Diluted magnetic semiconductors possessing intrinsic static magnetism at high temperatures represent a promising class of multifunctional materials with high application potential in spintronics and magneto-optics. In the hexagonal Fe-doped diluted magnetic oxide, 6H-BaTiO3-δ, room-temperature ferromagnetism has been previously reported. Ferromagnetism is broadly accepted as an intrinsic proper...
Through first-principles full-potential linear muffin-tin orbital (FP-LMTO) method within the local density approximation, we investigate the structural and electronic properties of Zn1-xMnx Y (VIa) where Y represent an element of the VIa column(S, Se and Te) compounds-based diluted magnetic semiconductors (DMS) in the Zinc-blend structure. We have investigated the lattice parameters and band g...
