Abstract: Ferromagnetism of La 0.67 Sr 0.33 MnO 3 is extremely sensitive to external perturbations like substrate-induced strain, charge injection and chemical interactions with neighbour layers. In this paper we discuss the perturbation induced by the presence of a metallic overlayer, typically deposited for electric contacts, in the prototypical case of the Au/La 0.67 Sr 0.33 MnO 3 interface. In particular we found a sizable decrease of the Curie temperature in thin films of La 0.67 Sr 0.33 MnO 3 after gold capping: …
