Abstract

Abstract Single crystals of oxide diluted magnetic semiconductor Zn1–x Mnx O have been grown by chemical vapour transport and thin films of Zn1–x Mnx O, Zn1–x –y Mnx Fey O have been deposited by pulsed laser ablation and rf magnetron sputtering methods. Optical absorption spectra of the obtained crystals and films have features associated with band‐to‐band direct type transitions and d–d crystal‐field transitions due to presence of Mn2+ ions. The observed peculiarities of the Faraday rotation for Zn1–x Mnx O crystals and films suggest of paramagnetic behaviour. In contrast, Zn1–x –y Mnx Fey O film samples exhibit ferromagnetic‐like behaviour which is confirmed on typical magnetic field dependence of the Faraday rotation at room temperature.
