Abstract:
Zn1−xMnxO (0 ≤ x ≤ 0.1) thin films were grown on sapphire substrates by pulsed laser
deposition and rf magnetron sputtering methods. As a target source ceramic pellets prepared by
mixing ZnO and Mn3O4 powders were used. The shift of the absorption edge due to increase the
energy band gap with increasing Mn content was observed in optical absorption spectra of the
Zn1−xMnxO thin films. Magnetic susceptibility and magneto-optical Faraday rotation experiments
show paramagnetic behavior and absence of ferromagnetic ordering in the studied films.
