Rezumat

Epitaxial La-deficient ultrathin films of La1-5MnO3 (LMO) were grown by a metalorganic aerosol deposition technique with monolayer accuracy on SrTiO3 (STO) substrates and engineered by using different interfacial layers. The role of LaO-TiO2 interface in the formation of the ferromagnetic metallic state in very thin LMO films was demonstrated. The ferromagnetic metallic ground state in LMO films with the thickness down to 6 monolayers is stabilized by a combination of a La-deficiency and the interface-induced doping.
