TL;DR

This study uses density functional theory to investigate how the thickness of a ferroelectric BaTiO3 layer influences the electronic and magnetic properties at its interface with LaMnO3.

Contribution

It provides new insights into the relationship between ferroelectric layer thickness and interface properties in BaTiO3/LaMnO3 heterostructures.

Findings

Ferroelectric overlayer thickness affects interface electronic states.

Magnetic properties are modulated by ferroelectric layer thickness.

Density of states analysis reveals interface electronic structure changes.

Abstract

By means of ab initio calculations within the density functional theory (DFT) electronic and magnetic properties of BaTiO3/LaMnO3 interface were investigated. An impact of ferroelectric overlayer thickness onto the interface properties was analysed through the spin-polarized density of states.
