Abstract
- In this study, we aim to synthesize novel materials that show ferromagnetic and ferroelectric properties with the magnetoelectric effect at room temperature. Nine types of superlattice were fabricated by stacking [7 units — ABO<subscript>3</subscript>/7 units — REMO<subscript>3</subscript>] for 14 times by pulsed laser deposition. From all reciprocal space mappings (RSMs) of the CaMnO<subscript>3</subscript> (CMO) superlattices, the satellite peaks were clearly observed. The calculated in-plain lattice parameter was 0.382 nm longer than 0.3732 nm, which is the bulk CMO and in-plain lattice parameter of the CMO thin film grown on SrTiO<subscript>3</subscript> (001) substrate. All the CaFeO<subscript>3</subscript> (CFO) series superlattices showed that the satellite peaks and Laue oscillations were clearly observed from the XRD 2θ–θ spectra. In the case of [CFO/BiFeO<subscript>3</subscript> (BFO)] superlattices, the number of deposited units of CFO in [CFO/BFO] one cycle was 6.94, which was quite close to the seven units that we aimed. The in-plain lattice constant of all the CFO series superlattices was fitted to that of the substrate. From RSMs of the [LaMnO<subscript>3</subscript> (LMO)/BFO] superlattice, the lattice parameter of the superlattice was fitted to that of the substrate in-plain. The cube-on-cube growth was confirmed in these LMO series superlattices. [ABSTRACT FROM AUTHOR]
