Influence of oxygen vacancies on the structural, dielectric, and magnetic properties of (Mn, Co) co-doped ZnO nanostructures
(Journal of Materials Science: Materials in Electronics, 2018)
Room temperature ferromagnetism promoted by defects at zinc sites in Mn-doped ZnO
(Elsevier B.V., 2016-01-15)
The nature of the room temperature ferromagnetism in dilute magnetic oxides is still a matter of debate. However, there is a consensus that structural point defects play an important role to achieve a desired long range ...
Structural and optical properties of ZnO and manganese-doped ZnO
(Elsevier Science Sa, 2016-12-29)
The structural, morphological and optical properties of manganese oxides supported on commercial ZnO,prepared by impregnation with manganese nitrate, were investigated. The nominal compositions of Mnin the samples were 5, ...
Photoluminescence and Magnetism in Mn2+-Doped ZnO Nanostructures Grown Rapidly by the Microwave Hydrothermal Method
(Amer Chemical Soc, 2013-12-12)
Zn1-xMnxO nanostructures were synthesized via the microwave-assisted hydrothermal method, which rapidly produces particles of controlled size and morphology. Samples were analyzed considering the effects of manganese ion ...
Influence of reducing heat treatment on the structural and magnetic properties of MnO:ZnO ceramics
(2021-05-15)
Polycrystalline MnO:ZnO bulk ceramics with a Mn proportion of 6, 11, 17 and 22 at% are prepared through a solid-state reaction and subjected to a heat treatment in a reducing atmosphere (Ar (95%) and H2 (5%)). The samples ...
Effect of Mn in ZnO using DFT calculations: Magnetic and electronic changes
(Elsevier Science Sa, 2019-07)
First principles calculations based on density functional theory (DFT)implemented in the VASP code was applied to study the structural, electronic and magnetic properties of ZnO and Mn-doped ZnO. Lattice parameters, bond ...
In situ formation of coloured M(II)–doped Zn2SiO4–willemite in ceramic glazes (M=Mn, Co, Ni, Cu)
(Elsevier, 2014-04)
The family of M(II) substituted ZnO–wurtzite was investigated as potential new ceramic pigments. When MxZn1−xO or (MM׳)xZn1−xO with (M/M′=Mn, Co, Ni, Cu) oxides are incorporated to industrial frits the development of new ...
Local and global magnetic properties of Zn1-xCoxO and Mn-doped GaAs thin films
(Institute of Electrical and Electronics Engineers (IEEE), 2006-10-01)
Amorphous and crystalline thin films of Mn-doped(0.5%-10%) GaAs and crystalline thin films of Zn1-xCoxO(x = 3%-20%) were investigated by means of magnetic susceptibility and electron spin resonance (ESR). For the Mn-doped ...
