In this paper, we are reporting the magnetic behavior of Cu-doped CeO2 films grown on single crystal LaAlO3(001) substrates. The Ce1-xCuxO2 films with x=0.03 and 0.15 were deposited by a pulsed laser deposition technique and were thoroughly characterized using high resolution x-ray diffraction, x-ray photospectroscopy, ultraviolet-visible absorption spectroscopy, and magnetic property measurements. All the characterization experiments showed the films to be of high quality, epitaxial, and free of any secondary phases. Detailed structure-property correlation analysis revealed the observed ferromagnetic property to be the intrinsic property of the material.
