论文摘要
通过从头开始计算，研究了可切换自旋的二维电子气体（2DEG）在抗磁磁性和铁电钙晶（即lamno3/batio3 superlattice）界面处的可能性。我们证明，在带有TIO2/LAO界面层的异质结构上，二维导电状态主要位于界面MNO层中。 Fermi级别的状态密度可以通过铁电偏振逆转来调节。导电状态与磁性共存主要来自Mn原子。
By means of ab initio calculations the possibilities of switchable spin-polarized two-dimensional electron gas (2DEG) at the interface of antiferromagnetic and ferroelectric perovskites, i.e., LaMnO3/BaTiO3 superlattice, were investigated. We demonstrate that at the heterostructure with TiO2/LaO interfacial layers the two-dimensional conducting state arises mainly localized within the interfacial MnO layer. The density of states at the Fermi-level can be tuned by ferroelectric polarization reversal. The conducting state coexists with magnetic one mainly arose from Mn atoms.
