Abstract (EN): This work is addressed to studying GdMnO3 thin films, prepared by a chemical solution method on oriented Pt substrates. Alterations regarding structure and magnetic response of both ceramics and single crystals show that the behaviour of the as-prepared films can be understood by assuming a continuously changing of the in-plane stress state in the film induced by mechanical coupling with the substrate. The emerging of a ferromagnetic response in the thin films is a consequence of the structural deformations induced by matching both film and substrate during the growth process, which alters the balance between competitive antiferromagnetic and ferromagnetic interactions.
