Strain-induced ferromagnetism and magnetoresistance in epitaxial thin films of LaCoO 3 prepared by polymer-assisted deposition

High quality epitaxial thin films of LaCoO3 on SrTiO3 have been prepared by spin-coating of a metal/polymeric aqueous solution. The films (≈ 17 nm) are homogeneous and smooth over large areas. The characteristic low-spin (LS) state is replaced by a higher spin configuration of Co(III), due to strain...
