Stronger Photo-Induced Effect in Epitaxial Thin Films of Small-Bandwidth Manganite Pr1−x Ca x MnO3 Compared to the Polycrystalline Bulk

Abstract

Photo-induced magnetization has been studied in small-bandwidth manganite Pr1−x Ca x MnO3 (x = 0.1) (PCMO) bulk and thin films. It is observed that the persistent change in magnetization under optical excitation is much stronger in epitaxial thin films of PCMO compared to the bulk. This change is manifested in a change of both coercive field and Curie temperature of the thin films. Stronger photo-induced effect in the thin films might have their origin in the substrate-induced strain effect on the magnetic properties.
