Ab-initio approach to the stability and the structural, electronic and magnetic properties of the (001) Znfe2O4 surface terminations
Karen L. Salcedo Rodríguez, Jhon J. Melo Quintero, Hugo H. Medina +6
We present a Density Functional Theory (DFT) based study of the structural and magnetic properties of the (001) surface of the semiconducting oxide ZnFe2O4 (spinel structure). The…
First-principles investigations of the magnetic phase diagram of GdCaMnO
Hichem Ben Hamed, Martin Hoffmann, Waheed A. Adeagbo +5
We studied for the first time the magnetic phase diagram of the rare-earth manganites series GdCaMnO (GCMO) over the full concentration range based on density f…
Tuning the probability of defect formation via substrate strains in SrFeMoO films
Waheed A. Adeagbo, Martin Hoffmann, Arthur Ernst +4
Since oxide materials like SrFeMoO are usually applied as thin films, we studied the effect of biaxial strain, resulting from the substrate, on the electronic and magnetic…
Study of the Negative Magneto-Resistance of Single Proton-Implanted Lithium-Doped ZnO Microwires
I. Lorite, C. Zandalazini, P. Esquinazi +14
The magneto-transport properties of single proton-implanted ZnO and of Li(7\%)-doped ZnO microwires have been studied. The as-grown microwires were highly insulating and not magnet…
Room temperature p-induced surface ferromagnetism
Guntram Fischer, Nadiezhda Sanchez, Waheed A. Adeagbo +6
We prove a spontaneous magnetization of the oxygen-terminated ZnO (0001) surface by utilizing a multi-code, SIESTA and KKR, first-principles approach, involving both LSDA+U and sel…
Lattice dynamics and structural stability of ordered Fe3Ni, Fe3Pd and Fe3Pt alloys
Markus E. Gruner, Waheed A. Adeagbo, Alexey T. Zayak +2
We investigate the binding surface along the Bain path and phonon dispersion relations for the cubic phase of the ferromagnetic binary alloys Fe3X (X = Ni, Pd, Pt) for L12 and DO22…
