Autor: Abdelkader Boukortt, S. Meskine, D.E. Aimouch, Ali Zaoui

Publikováno v: Journal of Magnetism and Magnetic Materials. 451:70-78

In this study, structural, electronic and magnetic properties of Mn doped (ZnO:Mn) and (Mn,Cr) co-doped zinc oxide (ZnO:(Mn,Cr)) have been calculated with the FP-LAPW method by using the LSDA and LSDA+U approximations. Going through three configurati
