Structure and magnetic properties of Co–CeO2 thin films deposited by PLD on Al2O3 (0001) substrates

Co–CeO2 films with the stoichiometry of Co0.03Ce0.97CeO2−δ were deposited by pulsed laser deposition (PLD) method on Al2O3 (0001) substrate, the structural, magnetic, and magneto-optical properties were investigated. The films show a ceria single phase with (111) preferred orientation. Magnetic meas...

Description
Summary:Co–CeO2 films with the stoichiometry of Co0.03Ce0.97CeO2−δ were deposited by pulsed laser deposition (PLD) method on Al2O3 (0001) substrate, the structural, magnetic, and magneto-optical properties were investigated. The films show a ceria single phase with (111) preferred orientation. Magnetic measurements confirm the ferromagnetism at room temperature, which is anisotropic with an out-of-plane magnetization easy axis. Magneto-optical measurements exhibit a giant Faraday rotation of 4800deg/cm in the direction perpendicular to the film plane.
