Abstract:
Single phase Pb(Ti(0.8)Fe(0.2))O(3-δ) thin films with a thickness of 210 nm and 120 nm were fabricated on Pt/Ti/SiO(2)/Si substrate by a chemical solution deposition technique. The thin film with a thickness of 210 nm showed a homogeneous microstructure, low porosity, low oxygen vacancies, and preferred orientation. It had negligible leakage current and well saturated ferroelectric hysteresis loop compared with the Pb(Ti(0.8)Fe(0.2))O(3-δ) bulk sample. Polarization fatigue characteristic indicated that this film has a potential application as a switcher in some electrical devices. The saturation magnetization in the Fe-doped PbTiO(3) film is weaker than that for bulk sample, and its ferromagnetism is correlated to the F-center exchange (FCE) mechanism. The present results revealed the multiferroic nature of the Pb(Ti(0.8)Fe(0.2))O(3-δ) thin film.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
