Microstructural, magnetic, and transport properties of as-deposited La0.9Ce0.1MnO3 films prepared by pulse laser deposition have been investigated. The high-resolution electron-microscopy study reveals that films have a high c-oriented texture with a negligible quantity of CeO2 inclusions. The observed Griffiths-type magnetic behavior above the Curie point and the partial transition of the film into the antiferromagnetic state with decreasing temperature are attributed to the microstructural peculiarities.
