Enhanced magnetic properties in ZnCoAlO caused by exchangecoupling to Co nanoparticles
Qi Feng, Wala Dizayee, Xiaoli Li +12
Wereport the results of a sequence of magnetisation and magneto-optical studies on laser ablated thin films of ZnCoAlO and ZnCoO that contain a small amount of metallic cobalt. The…
On Using Magnetic and optical methods to determine the size and characteristics of nanoparticles embedded in oxide semiconductors
Gillian A. Gehring, Harry J. Blythe, Qi Feng +5
Films of oxides doped with transition metals are frequently believed to have magnetic inclusions. Magnetic methods to determine the amount of nanophases and their magnetic characte…
Magneto-optical properties of Co/ZnO multilayer films
David S Score, Marzook Alshammari, Qi Feng +6
Multilayer films of ZnO with Co were deposited on glass substrates then annealed in a vacuum. The magnetisation of the films increased with annealing but not the magnitude of the m…
Two magnetic regimes in doped ZnO corresponding to a dilute magnetic semiconductor and a dilute magnetic insulator
A. J. Behan, A. Mokhtari, H. J. Blythe +5
Films of ZnO doped with magnetic ions, Mn and Co and, in some cases, with Al have been fabricated with a very wide range of carrier densities. Ferromagnetic behaviour is observed i…
