Abstract
LaMnO 3(LMO)/SrMnO 3(SMO)/NdMnO 3(NMO) superlattice with a broken inversion symmetry was fabricated by laser molecular beam epitaxy (laser MBE). Epitaxial LaMnO 3(LMO), SrMnO 3(SMO) and NdMnO 3(NMO) layers were alternately deposited on step-and-terrace structured SrTiO 3(STO) single crystal substrate with conductive La 0.5Sr 0.5CoO 3 (LSCO) layer. The stacking period of the LMO/SMO/NMO superlattice was varied from 1 to 44 unit cells, In the growth of LMO/SMO/NMO superlattice, the layer-by-layer growth was confirmed by in-situ monitoring by reflection high-energy electron diffraction (R.HEED) through RHEED intensity oscillation. Synchrotron X-ray diffraction along with the in-situ monitoring by RHEED revealed that LMO/SMO/ NMO artificial superlattices with very smooth interface between the layers were successfully fabricated by laser MBE.
