钙钛矿超晶格（SL）由于其丰富多样的物理性质而引起了人们的极大兴趣。在这项研究中，通过控制原子单层的数量，使用脉冲激光沉积（PLD）生长外延 LaMnO3/LaScO3 SL。拉曼光谱与 X 射线衍射倒易空间图相结合证实，LaScO3 的引入抑制了 SL 中的 Jahn-Teller 畸变。电传输测量揭示了热激活单间隙行为，该行为主要取决于 LaMnO3 层的厚度。磁测量表明，SLs 的磁性能与 LaMnO3 和 LaScO3 层的比例有关。这些结果有利于进一步了解LaMnO3基SL的电子和磁性能。
Perovskite superlattices (SLs) have attracted considerable interest owing to their rich and diverse physical properties. In this study, epitaxial LaMnO3/LaScO3 SLs were grown using pulsed laser deposition (PLD) by controlling the number of atomic monolayers. Raman spectroscopy combined with x-ray diffraction reciprocal space maps confirmed that the introduction of LaScO3 suppressed Jahn–Teller distortion in the SLs. Electrical transport measurements revealed a thermally activated single-gap behavior which mainly depended on the thickness of LaMnO3 layers. Magnetic measurements indicated that the magnetic properties of the SLs were related to the proportions of LaMnO3 and LaScO3 layers. These results are beneficial for the further understanding of the electronic and magnetic properties of LaMnO3-based SLs.
