Preparation and some properties of pulsed laser deposited YFeO3 films

Abstract YFeO 3 orthoferrite films have been deposited on to quartz and sapphire substrates by pulsed laser deposition. The films crystallize when annealed at temperatures in the range 750 to 900°C. The perpendicular hysteresis loops are rectangular with a maximum coercivity of 9 kOe. The Faraday rotation at 633 nm wavelength is in the range 4–5 × 10 3 deg/cm.
