摘要：

Co-CeO2 films with the stoichiometry of Co0.03Ce0.97CeO2-delta were deposited by pulsed laser deposition (PLD) method on Al2O3 (0 00 1) substrate, the structural, magnetic, and magneto-optical properties were investigated. The films show a ceria single phase with (1 1 1) 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 4800 deg/cm in the direction perpendicular to the film plane. (c) 2013 Elsevier B.V. All rights reserved.
