Effects of oxygen-reducing atmosphere annealing on LaMnO<sub>3</sub>epitaxial thin films
We investigated the effects of annealing on LaMnO3 epitaxial thin films grown by pulsed laser deposition (PLD) and propose an efficient method of characterizing their stoichiometry. Structural, magnetic and optical properties coherently indicate non-stoichiometric ferromagnetic and semiconducting phases for as-grown LaMnO3 films. By annealing in an oxygen-reducing atmosphere, we recovered …
