Enhanced indirect ferromagnetic p-d exchange coupling of Mn in oxygen rich ZnO:Mn nanoparticles synthesized by wet chemical method
This paper investigates the ferromagnetism in ZnO:Mn powders and presents our findings about the role played by the doping concentration and the structural defects towards the ferromagnetic signal. The narrow-size-distributed ...
Alteration of Mn exchange coupling by oxygen interstitials in ZnO:Mn thin films
The un-doped and Mn doped ZnO thin films, with oxygen rich stoichiometry, were deposited onto Si (1 0 0) substrate using spin coating technique. The structural analysis revealed the hexagonal wurtzite structure without any ...
Elimination of impurity phase formation in FePt magnetic thin films prepared by pulsed laser deposition
The formation of impurity phases in FePt thin films severely degrades its magnetic properties. The X-ray diffraction patterns of FePt thin films, synthesized using pulsed laser deposition (PLD), showed peaks corresponding ...
Entrapping of inclusions within carbon nanotubes during catalytic decomposition of C2H4 on a “thick” nickel film
To understand the formation mechanism of catalyst inclusions in carbon nanotubes, multi-walled carbon nanotubes were grown via catalytic decomposition of C2H4 on a 50-nm-thick nickel film at 725 C. Atomic force microscopy, ...
