Interfacial Magnetoelectric Coupling in Tri-component Superlattices
Jaekwang Lee, Na Sai, Tianyi Cai +2
Using first-principles density functional theory, we investigate the interfacial magnetoelectric coupling in a tri-component superlattice composed of a ferromagnetic metal (FM), fe…
Magnetoelectric Coupling and Electric Control of Magnetization in Ferromagnet-Ferroelectric-Metal Superlattices
Tianyi Cai, Sheng Ju, Jaekwang Lee +6
Ferromagnet-ferroelectric-metal superlattices are proposed to realize the large room-temperature magnetoelectric effect. Spin dependent electron screening is the fundamental mechan…
Absence of Critical Thickness in an Ultrathin Improper Ferroelectric Film
Na Sai, Craig J. Fennie, Alexander A. Demkov
We study the ferroelectric stability and surface structural properties of an oxygen-terminated hexagonal YMnO ultra-thin film using density functional theory. Under an open cir…
Spin-Filtering Multiferroic-Semiconductor Heterojunctions
Na Sai, Jaekwang Lee, Craig J. Fennie +1
We report on the structural and electronic properties of the interface between the multiferoic oxide YMnO and wide band-gap semiconductor GaN studied with the Hubbard-corrected…
