Griffiths phase and charge ordering in electron-doped La_(0.9)Ce_(0.1)MnO_3 films

摘要

Microstructural, magnetic, and transport properties of as-deposited La_(0.9)Ce_(0.1)MnO_3 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 CeO_2 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.
