Abstract

Trilayer structures of La2/3Sr1/3MnO3 (LSMO), SrTiO3 (STO) and YBa2Cu3O7−δ (YBCO) films were deposited by laser ablation under different conditions and investigated by AFM, XRD, SIMS and magnetic dusceptibility measurements. It was demonstrated by AFM that single LSMO films are smoother than YBCO and for this reason these are preferable as first layer on the substrate. But the crystal lattice perfection of an HTS film, when on the top, is slightly reduced, as detected by XRD. The “in-situ” deposition of all three layers resulted in oxygen-deficient YBCO films. We found that “ex-situ” annealing in oxygen increases the superconducting transition temperature and does not cause deterioration of the LSMO film magnetic properties.
