(a) Field-cooled magnetization of the YBCO–LCMO–YBCO trilayer sketched in the inset in a magnetic field applied parallel to the layers. (b) Hysteresis loop at .
(a) -corrected cross-sectional HRTEM image of the central area of the YBCO–LCMO–YBCO trilayer, comprising the entire 7 u.c. thick LCMO layer and both interfaces. (b) Model of the atomic positions in the trilayer. Two clippings of the simulated images of bulk YBCO and LCMO based on the atomic model are superimposed on the experimental image (labeled by dotted lines at the top left corner and center left), which clearly show the respective atom column under the experimental conditions. (c) Line profiles of the image intensity [from A to B and from C to D in panel (a)] averaged over a rectangular area of length 6.0 nm. The interfacial planes are highlighted by red fonts in panel (a) and by black lines in panel (b).
(a) Amplitude and (b) phase of the reconstructed EPW of the YBCO–LCMO–YBCO trilayer. The YBCO unit cell is displayed as an inset in panels (a) and (b). The insets in panel (b) also show the results of the simulation for the upper and lower interface configurations shown on the right hand side, for a specimen thickness of 8.6 nm. White lines indicate the corresponding planes in panels (a) and (b).
