Obtaining iron-oxide films on sapphire substrates

Iron-oxide films on sapphire substrates were obtained using laser radiation with 1064-nm wavelength and studied by methods of scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission Mössbauer spectroscopy. The obtained Fe$_{2}$O$_{3}$ films probably occur in a superparamagnetic state and may find application in gas sensors and various magnetic devices.
